Audiolec offers customized solutions for Sound Proof/Sound Testing/ Anechoic chambers.

Sound Proof/Sound Testing chambers create acoustically quiet, non reflecting space, insulated from outside noise. Such a quiet space is used for accurate measurement of noise generated by machines, HVACs, motors, refrigerators. These are also used in Audiometry.

Smaller sound proof chambers are built of MS walls lined with glass/rock wool and acoustic tiles.

Anechoic chambers provide low noise environment, very high internal sound absorption and very low reverberation time for a range of audio frequencies. Anechoic chambers are used for measurements on loudspeakers and microphones.

Anechoic chambers are generally built of brick walls. These walls are lined with wedges (shown below) of high density glass wool. These wedges 'absorb' incident sound, thus creating a reflection free space.
