Announcement of the establishment of the Audio Business Division

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.

• Other construction services

We measure and evaluate how much sound is blocked by the building's partition walls and floors.

Generate pink noise in the sound source room, measure the sound pressure levels on the source side and the receiving side, and determine the inter-room sound pressure level difference. From the results, calculate the D value and evaluate it.

• Other construction services

We will design the necessary sash grade for the indoor target values.

It predicts the noise level exposed on the window surface based on the frequency data of the sound source, its position, size, and occurrence frequency, and calculates the necessary sound insulation required to achieve the target value indoors.

• Other construction services

You can easily conduct sound insulation performance tests for building materials at a low cost.

"I want to know the sound insulation performance of building materials under development," "I can't spend too much on costs," "I want to know the results as soon as possible." If you have such needs, please consult us. It has become easy to conduct sound insulation performance tests for building materials at our acoustic laboratory. (The data is not official. Please be sure to use it as reference data.)

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).

Experts in sound provide total support from measurement to countermeasures. Leave the noise control construction for factories to us.

In factories and similar environments, the issue of "sound" has become inseparable. At Environmental Research, we provide comprehensive support from noise control measures for equipment to the design and construction of soundproof walls, solving sound-related problems.

• Other construction services

We will measure the reverberation time of the music room, gymnasium, conference room, and other spaces.

Sound sources are generated from the speakers, and data is recorded from microphones placed in several locations within the room. From the analysis results, the reverberation time of the room is calculated.

The "HM-S6" is an embedded park sensor that detects vehicles through changes in magnetic flux and responds to various situations from passing to stationary vehicles. It can be used for the opening and closing of input doors at waste treatment plants, as well as for gates that vehicles pass through and outdoor parking applications. It can also be installed on rebar and steel plates. 【Features】 ■ Resistant to the effects of natural environments such as rain, snow, temperature changes, and geomagnetism ■ Protection rating IP68 reduces the risk of water ingress ■ Ten times the load capacity compared to conventional embedded park sensors (based on our comparison) ■ Can distinguish between vehicles even when they pass continuously ■ Can be installed on rebar and steel plates *For more details, please refer to the PDF document or feel free to contact us.

At a cabaret club located in Tokyo, we have introduced our diffusers to create a fragrant atmosphere within the floor.
