The SoundEar-V device itself consists of a microphone, a small sound level meter and acoustic processor, all enclosed in a small case similar to a USB memory stick. This can be plugged directly into the computer's USB port or be connected using the cable supplied.
The microphone, which is enclosed in the SoundEar-V case, picks up and amplifies the tiny fluctuations in air pressure that are sound.
Inside the main body of the unit is a small sound level meter. This converts the signal from the microphone into a more usable unit, the decibel, dB(A). The levels measured are filtered to give a response similar to the human ear.
The SoundEar-V connects to the computer using the standard USB port. It can be plugged directly into the side (handy for laptops) or using the cable provided.
The SoundEar-V should be mounted reasonably close to the source of the noise or in the area where the noise is a problem. On the side of a computer monitor is usually the best place.
The kit includes velcro patches for mounting the SoundEar-V on a monitor.
