The regulations for buildings focused on the measuring method and assessment procedure for the room sound pressure level difference, floor impact sound level and room noise level in accordance with intended use are stipulated by JIS and Architectural Institute of Japan (AIJ). Also the regulations for exterior noise/vibration level are stipulated by 'environmental quality standard' and 'noise/vibration regulation law'.
Acoustical Measurement for Multiple Dwelling
We investigate the noise by conducting the measurement such as pre-environmental noise measurement in planning property, the measurement of light/heavy floor impact sound level, sound pressure level difference, the indoor noise level at the completion stage, the measurement of squeak and rattle/mysterious sound after delivery.
Acoustic Measurement for Business Premises
We investigate to improve sound insulation characteristics in the executive/reception room and conference room which requires privacy for business and to improve the sound field characteristics in a large conference room/meeting corner.
Acoustic Measurement for Factory
Our omni-directional sound source analyzing system called 'Noise Vision' can detect noise sources from factory on the boundary line and search an annoying noise source affect to workers in factory.
Other Acoustic Measurement
We also investigate noise/vibration level from the road, railroad and construction work as well as review the acoustic performance of building such as music hall, movie theater, hotel and so on.
