We measure and evaluate the indoor quietness in buildings.
We measure and analyze the road noise that penetrates from outside, as well as the noise generated during the operation of elevators and mechanical parking systems, in order to evaluate the indoor quietness based on the analysis results (such as NC curves).
Quantifying invisible sounds and concerning vibrations! Conducting investigations such as cause analysis measurements and sound insulation measurements!
Our company conducts "Noise and Vibration Level Measurements." We can measure the "working environment sounds in factories" aimed at preventing hearing impairments for workers, as well as "noise and vibration measurements of machinery" and "noise and vibration level measurements in factories." Additionally, we conduct investigations such as "cause investigation measurements" and "sound insulation measurements," where we measure the specific frequencies of equipment generating noise and investigate the surrounding impact based on those frequencies. 【Features】 <Measurement of Working Environment Sounds in Factories> ■Measurement Locations: Areas around equipment that generates high noise ■Purpose: Prevention of hearing impairments for workers ■Relevant Legislation: Labor Safety and Health Act (under the jurisdiction of the Ministry of Health, Labour and Welfare) *For more details, please refer to the PDF materials or feel free to contact us.
We will measure and evaluate how loud the standard floor impact is heard in the room below.
Using lightweight and heavyweight impact sound sources (tapping machine and banging machine), the floor being measured is excited to generate impact sound, and the lightweight equivalent sound pressure level and heavyweight maximum sound pressure level are measured directly below. The floor impact sound level is then determined. From these results, the L value is calculated and evaluated.
