Sound Amplifiers and Audio Equipment for Surveillance Investigations
What is an Audio Amplifier or Sound Amplifier?
An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals composed primarily of frequencies between 20 – 20 000 Hz, the human range of hearing) to a higher level. The equipment can be used either indoors or outdoors to listen to sounds and conversations at a distance.
While the input signal to an audio amplifier may measure only a few hundred microwatts, its output may be tens, hundreds, or even thousands of watts.
Sound Amplifier Systems
A Sound Amplification System enables private investigators and police officers to hear conversations that are taking place in a nearby location, such as in another room, or on the other side of the park. This allows private investigators to listen to what is being said without the other party’s knowledge. The basic point is to be able to hear what is being discussed while remaining unseen. Audio amplification systems can be used for many other purposes, such as eavesdropping on telephone conversations, or checking up what the kids are doing in the backyard.
The typical equipment that is included with the sound amplification tool includes: the listening device, the “sound catching” cone, microphone, mounting clips, batteries, carrying and storage cases. In addition, some packages include audio out jacks and cables to record conversations. Also, many packages include noise reduction and wind reduction capabilities to help filter out unwanted background noise. This can be helpful when playing back the recording.
The amplification devices can be targeted by pointing the unit in the direction of the sounds you are interested in. The sounds that are targeted are then amplified as much as 10 times.
In addition to surveillance uses, the listening tools can also be used for nature observation, concerts, hunting, bird watching, listening to lectures, personal security, sporting events or even simply watching TV. The listening distance will vary depending on the particular device you are using, but count on being able to pick up conversations from over 300 yards away.
As a protection mechanism, some units come equipped with auto shutoff in case the sound becomes suddenly too loud.
