Identification of over 500 sounds by categories

Understandable categories
Domestic, neighborhood, equipment, exterior, transport, urban activities...
Usual vs atypical sounds
Sonalyze distinguishes usual sounds from atypical sounds, to help prioritize what deserves action.
Reading by room
Sonalyze offers a reading by room to locate the most sensitive areas.
Decibels and 'which sound?': the correlation that changes everything
Sonalyze associates a sound level (in decibels) with each type of sound to measure the real impact of each nuisance.
Association of a sound level with each type of sound identified
Differentiation between a frequent but low sound and a rare but very annoying sound
Average levels, peaks, percentiles, night windows, exposure duration
IEC and ISO standards: Sonalyze relies on measurement principles compliant with IEC and ISO standards, to guarantee a serious and consistent approach.
