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.

• Contract measurement

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 calculate the inter-room sound pressure level difference. From the results, calculate and evaluate the D value.

• Contract measurement

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

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

• Contract measurement

It is possible to easily conduct sound insulation performance tests of 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. Our acoustic laboratory can easily conduct sound insulation performance tests for building materials. (The data is not official. Please use it as reference data only.)

• Contract measurement

We measure and evaluate the indoor quietness in buildings.

We measure the road noise that penetrates from outside, as well as the noise generated during the operation of elevators and mechanical parking systems indoors, and evaluate the indoor quietness based on the analysis results (such as NC curves).

• Contract measurement

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

In factories and similar settings, 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.

• Contract measurement

We will measure the reverberation time of the music room, gymnasium, conference room, and so on.

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

SPACECOOL Inc. has received the Excellence Award in the "JA Accelerator Program 8th Term," an open innovation program hosted by the "AgVenture Lab," an innovation lab by eight JA Group organizations nationwide, which supports startup companies with innovative ideas and technologies in the agriculture, forestry, and livestock sectors. In this program, startups that passed the preliminary screening from a record number of over 270 applications presented at the final selection meeting held on May 21, 2026. During this event, our company proposed a new solution utilizing the radiative cooling material "SPACECOOL" to maintain and improve productivity in the agriculture and livestock industry and to reduce the risk of heatstroke for agricultural workers, earning the Excellence Award. Due to the worsening heat waves associated with recent climate change, the importance of heat countermeasures in the agriculture and livestock industry has increased. Taking this recognition as an opportunity, our company aims to further contribute to various challenges related to heat in the agriculture and livestock sector through the radiative cooling material "SPACECOOL." Additionally, to accelerate our expansion into the agriculture, forestry, and livestock sectors, we will participate in the upcoming "Livestock Week" this month to recruit demonstration sites.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

On our company's website introducing vehicle detection sensors, you can easily find products that meet your needs from three categories: "Purpose of Use," "Location of Use," and "Product List." [Introduction to Vehicle Detection Sensors] The sensors detect the passage of vehicles and notify you with a rotating light or switch the display of parking availability. They contribute to safe driving within parking lots and smooth management operations. They are used in various areas, from coin parking to large-scale parking lots. We will continue to improve our webpage to provide information about Hotron's "Vehicle Detection Sensors."
