Sound insulation performance measurement and floor impact sound measurement

The basic methods for understanding a building's sound blockage performance are sound insulation performance measurement (sound pressure level difference between rooms and between specified paths) and floor impact sound measurement.
Although this measurement is generally performed upon building completion, analysis may be performed to ascertain a building's current situation when a sound leakage complaint is arise.
Nihon Onkyo Engineering provides acoustic measuring service according to the needs of customers.

Sound insulation performance measurement (sound pressure level difference between rooms and between specified areas)

Sound insulation measurement

Sound insulation measurement

Sound insulation performance measurement is used to measure how well the walls and floors between areas block sound. The results of the measurement are evaluated using an applied grade that relates to the sound pressure level difference between rooms and between specified paths.

Floor impact sound measurement

Floor impact sound measurement

Floor impact sound is noise that is generated when upper floors are struck, such as a chair dragging on an upper floor, or footsteps on an upper floor, that can be heard at lower floors. Floor impact sound measurement is performed in accordance with the standards.
