An Electronic listening device is a device designed to pick up voices and other sounds while remaining out of sight. For example, an Electronic listening device may be embedded in a pen, item of clothing, a piece of furniture, or electronic device that isn’t normally used for picking up the sound. Some Electronic listening devices are even designed for use in flower arrangements. Electronic listening device detector Miami Beach Coral Gables. Often, though not always, Electronic listening devices are used in combination with hidden cameras, allowing the user to hear and see events in the area without alerting others.

Talk of Electronic listening devices often brings images to mind of people spying on each other, but these microphone devices aren’t always used in that manner. Electronic listening device detector Miami Beach Coral Gables. They may be legitimately used on TV shows that have a host who needs to remain mobile, for example. In such a case, an Electronic listening device allows a TV host to move about as much as necessary and speak to his audience no matter where he goes on the set.

Sometimes a person may use an Electronic listening device to record the details of his own conversation. Electronic listening device detector Miami Beach Coral Gables. A journalist may use a microphone device pen, for example, to record the details of an interview and retain information provided off the record. Another party may use an Electronic listening device to record another person’s admission of guilt or threats.

There are also many ways in which Electronic listening devices may be used as a spy device. For example, an individual may suspect his spouse of adultery and install an Electronic listening device to record what she says while talking on the phone. Electronic listening device detector Miami Beach Coral Gables. He may even set one up to record what happens in their bedroom while he’s away from home. A parent may place such a microphone device in his teen’s bedroom in order to learn what he says in private conversation. An employer may even install an Electronic listening device to eavesdrop on what his employees are saying throughout the day. Electronic listening device detector Miami Beach Coral Gables.

It’s important to note that many jurisdictions make certain uses of Electronic listening devices illegal. In many places, it is illegal to record phone conversations without asking permission, even if the person is recording his own spouse. Electronic listening device detector Miami Beach Coral Gables. Placing an Electronic listening device in another person’s home, office, or private space may be considered illegal as well. On the other hand, law enforcement officials in many jurisdictions are permitted to use Electronic listening devices to solve cases and record confessions, but they typically have to secure a court’s permission to do so.

While bigger part of all inhabitants of our planet is nice people, there are still enough bad guys which can annoy you or even put you in danger. Electronic listening device detector Miami Beach Coral Gables. Among those bad guys might be your business competitors, jealous neighbors, ex-boyfriends or ex-girlfriends, and even members of your own family. Any of those people can secretly install hidden camera or microphone device to record video and audio materials about you and then use them with bad intentions or just to their advantage. Let us explain every case with more details.

If you have your own business, you definitely have competitors. Electronic listening device detector Miami Beach Coral Gables. Some of them are sincere people who like the spirit of competition and honestly trying to make their products and services better to outmatch you and other competitors as well. The rest is a bunch of shady guys who will use any measures in order to become the number one in the industry. Among those measures might be industrial espionage or even blackmail, but to do that they need to hide some spy cameras to picture some videos or at least microphone device for eavesdropping. Electronic listening device detector Miami Beach Coral Gables. But if you have Bug Detectors in your hands, you will easily discover all hidden surveillance device in any room of the building.

The same applies to jealous neighbors, ex-boy or girlfriends and members of your family as well. Electronic listening device detector Miami Beach Coral Gables. All of them are trying to get some facts about your private life to use them later to their advantage. And again the best way for them to get those videos or audio records is to hide cameras or microphone devices inside your house. Those things are wireless because evildoers have no time to get wire so you can discover all electronic surveillance devices secretly placed inside your house with the help of products from this category. Electronic listening device detector Miami Beach Coral Gables.

Modern technological advances have led to the development of cameras so small that a spouse or boss can hide them practically anywhere. Electronic listening device detector Miami Beach Coral Gables. The same is true of microphone devices, many of which are sensitive enough to pick up a conversation in another room. Hidden cameras and microphone devices are a violation of your privacy if you are not aware of them. While there are many expensive and untested devices claiming to disable this device, there are a few simple things anyone can start with to protect their privacy at home or at work.

Detect the placement and the number of the hidden recording devices. Most methods for blocking these units requires you to target them directly. Use an electronic bug sweeper or manual methods to detect camera lenses. Electronic listening device detector Miami Beach Coral Gables.

Identify and remove items likely to contain a camera or microphone device. If someone has recently given you a new houseplant, stuffed animal or lamp, it may contain a hidden camera, according to Unified Solutions. Electronic listening device detector Miami Beach Coral Gables. Replace phones making unusual hissing or clicking noises with brand new units directly from a retailer.

Manually disable or cover cameras built into your devices. Cameras in laptops, smartphones, and other handheld devices are susceptible to outside control through viruses and tampering, warns computer programmer Marc Roessler. Electronic listening device detector Miami Beach Coral Gables.

Cover or muffle the device. Move a potted plant to block a camera lens or cover a microphone device with a wadded up rag to disrupt the recording. Electronic listening device detector Miami Beach Coral Gables. Remove it if you can, but in some cases covering it allows you time to gather evidence without alerting the person who installed the device.

Use a white noise generator. Play the radio loudly when having a private conversation on a tested and secure phone line. Security companies produce a number of white noise machines designed to transmit frequencies at a lower volume that affect the microphone device but still allow you to sleep without disruption. Electronic listening device detector Miami Beach Coral Gables.

Shine a basic red laser pointer directly at the lens of a hidden camera. Electronic listening device detector Miami Beach Coral Gables. The lens will reflect and magnify the beam, distorting what the camera records without damaging it permanently, according to video expert Mark Naimark.

There are systems that advertise White Noise and some that advertise Pink Noise; this section will address the difference.

White Noise has equal energy per frequency – the energy frequency spectrum is basically flat. Since human hearing responds in a logarithmic manner (see the previous graph), White Noise sounds to a human as if the high frequencies are loudest (the audio sounds “Brighter”). Electronic listening device detector Miami Beach Coral Gables.

Pink Noise has equal energy per frequency octave. The noise energy level decreases as frequency increases, or for example, there is the same amount of energy in each of the following frequency bands:

100 to 200 Hz. Electronic listening device detector Miami Beach Coral Gables.

200 to 400 Hz.   Electronic listening device detector Miami Beach Coral Gables.

400 to 800 Hz.   Electronic listening device detector Miami Beach Coral Gables.

800 to 1600 Hz.   Electronic listening device detector Miami Beach Coral Gables.

Pink Noise has a frequency roll-off similar to the human hearing capability and therefore sounds less bright and richer at the lower frequencies when compared to White Noise.

The Question: What is the best type of noise to use as an eavesdropping countermeasures?

The Solution: Defeat intelligibility of the spoken word in the surrounding perimeter (rather than simply create a pleasant sound environment). This goal generally takes more power and sound energy in the perimeter of the protected space. Electronic listening device detector Miami Beach Coral Gables.

Therefore, a  White Noise system is more generally appropriate because energy is evenly distributed and the higher frequency components (and thus the intelligibility) of the spoken word are more greatly impacted by the energy level in a white noise system. Electronic listening device detector Miami Beach Coral Gables.

What Is Sound Masking? Electronic listening device detector Miami Beach Coral Gables.

Sound masking is the addition of natural or artificial sound (such as white noise or pink noise) into an environment to cover up the unwanted sound by using auditory masking. This is in contrast to the technique of active noise control. Electronic listening device detector Miami Beach Coral Gables. Sound masking reduces or eliminates awareness of pre-existing sounds in a given area and can make a work environment more comfortable while creating speech privacy so workers can better concentrate and be more productive. Electronic listening device detector Miami Beach Coral Gables. Sound masking can also be used in the outdoors to restore a more natural ambient environment.

Sound masking can be explained by analogy with light. Imagine a dark room where someone is turning a flashlight on and off. The light is very obvious and distracting. Now imagine that the room lights are turned on. Electronic listening device detector Miami Beach Coral Gables. The flashlight is still being turned on and off but is no longer noticeable because it has been “masked”. Sound masking is a similar process of covering a distracting sound with a more soothing or less intrusive sound.

A document was published in 1980 by the Defense Intelligence Agency. It concerned the protection of secure facilities from deliberate audio surveillance; sound masking was one means of protection. Electronic listening device detector Miami Beach Coral Gables. A defense contractor developed a vibration device that could be attached to various surfaces such as doors, walls, and windows, to provide sound masking. In the 1980s, the another company developed a speaker that could not be distinguished from a fiberglass ceiling tile. The invisibility aspect was favorable to architects. The attempt was made to use this speaker for sound masking, but the cost and the sound radiating characteristics limited its use for that purpose. Electronic listening device detector Miami Beach Coral Gables.

The word “mask” means merely to cover up, or disguise, something. That something is not changed but simply hidden. Physical masks cover the face of the wearer. Deodorants mask odors; they do not eliminate them. One-way windows mask the persons on the other side so they are not visible. Electronic listening device detector Miami Beach Coral Gables. Sound can mask other sounds to cover them up. In every case, the objective is to hide something that exists, it does not eliminate them. Many people have heard of noise cancellation, but incorrectly believe that it is a form of sound masking. In noise cancellation, the sound is actually eliminated not covered up. So why not use it?

Unfortunately, this technique works only within spatially constrained areas, such as headphones, and is not applicable to entire rooms. What is sound masking trying to mask? It covers up conversations, by raising the background level. Electronic listening device detector Miami Beach Coral Gables. That level must be above the sound of conversations most of the time. How is that determined? For every situation, there is an optimum background sound level, just as there is an optimum light level. In the home that sound level is low, and at sporting events that level is high. The function of sound masking is to bring the background level up to the optimum; the level that provides fewer distractions without being a distraction itself. This requires persons experienced with this technique to find that optimum.

Why Use Sound Masking? Electronic listening device detector Miami Beach Coral Gables.

Sound masking has some unique advantages over traditional methods of reducing distracting sounds.

(1). Sound masking is dynamic (variable) as are the sounds it is intended to block. Building elements that provide sound attenuation are static (fixed) and cannot adapt to intruding sounds that change in level. Masking can vary from location to location as well as from time to time, to adapt to changing environmental conditions. Electronic listening device detector Miami Beach Coral Gables.

(2). Sound masking is by far the least expensive tool for providing privacy.

(3). Sound masking systems are special audio systems that create spatially uniform sound levels. Electronic listening device detector Miami Beach Coral Gables.

(4). Sound masking works at the listener’s ear and is independent of the building structure (acoustically) so concerns about how distracting sounds get from one place to another is unimportant. Structural modifications require such knowledge and are more costly. Electronic listening device detector Miami Beach Coral Gables.

Applications of Sound Masking. Electronic listening device detector Miami Beach Coral Gables.

(1). Closed Offices

Closed offices and conference rooms often appear to provide confidentiality but actually may not. Electronic listening device detector Miami Beach Coral Gables. Lightweight or movable, walls are more sound transparent and most do not extend to the ceiling deck, so speech can pass into the ceiling plenum and then to the next office. Sound masking can be used to make up for such acoustical weaknesses.

(2). Open Offices. Electronic listening device detector Miami Beach Coral Gables.

Open offices can have a background sound level that is too low. Sound level restrictions of air handling units are increasingly stricter. The conversations of others can be clearly understood. Sound masking raises the background level to make up for the absence of walls that would otherwise block the sound.

Placing Speakers in a Suspended Ceiling Plenum

The plenum is the space between a suspended ceiling and the structural deck above it. Since most offices have such spaces, sound masking speakers are commonly added there. For open offices, uniformity of the sound masking in the inhabited area is important and is largely determined by the spacing of the masking speakers. Electronic listening device detector Miami Beach Coral Gables. Speaker arrays are generally rectangular. They generally face upwards to reflect sound from the deck and broaden the distribution of the sound to create a more uniform sound field. There are other factors that determine the horizontal spacing of speakers to assist in creating a uniform sound level below. The first is the nature of the ceiling material.

Mineral tile ceilings have appreciable sound loss so speaker spacing of 15 feet is common. Fiberglass ceilings, on the other hand, are highly sound absorptive but are more sound transparent, requiring speakers to be closer. The second factor is the depth of the ceiling plenum. Electronic listening device detector Miami Beach Coral Gables. The deeper the plenum, the further apart the speakers can be placed. The third factor, of somewhat lesser importance, is the height of the suspended ceiling itself. With higher the ceilings sound uniformity is improved, so speaker spacing can be increased.

In An Open Ceiling. Electronic listening device detector Miami Beach Coral Gables.

In some offices, particularly warehouses that have been converted to office space, there is no ceiling plenum. Masking speakers are hung in a similar manner to those above suspended ceilings but the speaker spacing and height is different. Typically, the speakers are mounted higher and the spacing between them is closer. Electronic listening device detector Miami Beach Coral Gables.

The height of the structural ceiling above is a large factor in spacing, as is the presence or absence of sound absorbing materials on the ceiling surface. Reasonably good uniformity of sound masking can be achieved. Some office designs employ the use of scattered (as opposed to continuous) ceiling tiles (clouds). Careful design is needed to achieve reasonable sound masking uniformity.

Under Raised Floors. Electronic listening device detector Miami Beach Coral Gables.

Sound masking speakers can be placed under raised floors in offices that utilize them. To carry the weight above, the floor material is structurally strong and offers high attenuation of any sound below it. Experience has shown that not only is the uniformity of the sound above exceptionally good, but occupants are hard pressed to determine where the sound source is located (good diffusion -See Section 3.7.6). Electronic listening device detector Miami Beach Coral Gables.

One direction is a line between the speakers; the other direction is a line lateral to the speakers starting at the midpoint. If the depth of the cavity is sufficient, normal sound masking speakers can be used, otherwise, small speakers can be used; they fit into a cavity as small as 2 inches and radiate sound horizontally. If the cavity is used as a return air duct, care must be taken to shield the opening.

Face Down In A Suspended Ceiling. Electronic listening device detector Miami Beach Coral Gables.

The masking sound travels directly to a listener without any intervening sound attenuating materials. This arrangement, with speakers mounted in a suspended facing down, has been typical for paging systems but is being used more recently in some sound masking applications. The speaker for this application must be specially designed to have a wider spread of sound than other speakers to make up for the lack of intervening material. They are often called “direct field” speakers to distinguish them from the other arrays that radiate sound indirectly.

Electronic listening device detector Miami Beach Coral Gables. They can be small loudspeakers or entire ceiling tiles installed with hidden speakers. Although the speaker locations in the above sections are preferred, there are situations where the use of direct field speakers is necessary. An alternative location for such speakers is wall mounting.
