labBGN is the key hardware component for operating HEAD acoustics background noise simulation systems. With the hardware platform and the corresponding simulation software (3PASS lab, 3PASS flex, 3PASS reverb, HAE-BGN, HAE-car), it is possible to record, equalize and realistically playback background noises as well as reverberation (impulse responses) – reproducible across different laboratories.
labBGN provides a maximum of ten channels: Thus, users are able to connect e.g. eight loudspeakers and one stereo subwoofer to the labBGN concurrently.
In conjunction with the simulation software (3PASS lab, 3PASS flex, 3PASS reverb, HAE-BGN, HAE-car), microphone arrays MSA I or MSA II (recording, equalization) as well as loudspeakers and power amplifiers, labBGN forms a powerful background noise simulation system.
