Description
AUDIOSTAT is the only cost effective way of truly improving your sound system. The vast majority of today's sound systems are NON-REACTIVE to fluctuating levels of environmental noise with no means of automatic adjustments to maintain signal audibility, let alone intelligibility. AUDIOSTAT uses the latest digital signal processing (DSP) technology to transform your passive sound system into a reactive system that compensates seamlessly for any fluctuations in ambient noise.
AUDIOSTAT will significantly improve the audibility and intelligibility of your sound systems' output -and -it will never be too loud!

Architects and Engineers Specifications

The ambient noise compensation device shall automatically regulate the operating level of the sound system in response to fluctuating levels in the system's operating area. In this way the audio program shall always be at a preset level -background or foreground--relative to the ambient noise. In foreground mode, the program shall always be audible and intelligible without ever being too loud. The device shall employ digital signal processing circuitry, and be capable of compensating for pre-set levels of ambient noise fluctuations, up to a maximum of 22dB. The  device shall continuously measure the true signal to noise ratio, taking into account program level, spectrum and statistics, as well as noise level, spectrum and statistics- both as sensed in the sound field so as to incorporate the effects of the signal path and room acoustics. These signal and noise data shall be processed by an ear-brain model to determine the subjective impact on intelligibility and audibility as percieved by the ear. A variable fast response time shall ensure that signal level changes are not audible. The unit shall incorporate an independent sense microphone, located within the sound field to be affected., and not in any way isolated from the loudspeakers it controls. Frequency response: 50Hz to 100KHz +0/-0.5dB.   SNR: 80dB
