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.

• 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.

• Contract measurement

The glass pot lid has a hydrophilic heat-resistant coating, allowing you to check the cooking state without any fogging.

SPACECOOL Co., Ltd. is pleased to announce its support for the purpose of the newly established memorial day "Day to End the Too Hot Summer" by the Japan Climate Leaders Partnership (JCLP). In order to address the increasingly severe heat waves, we will continue to promote the expansion of our zero-energy cooling radiative cooling material "SPACECOOL." JCLP has registered August 8, 2025, and every August 8 thereafter, as "Day to End the Too Hot Summer" with the Japan Anniversary Association. — What is the new memorial day "Day to End the Too Hot Summer"? In recent times, many regions in Japan have been experiencing consecutive days of extreme heat, and the impacts of climate change are manifesting in serious ways in our lives. Nevertheless, reports and discussions linking this to "climate change" are limited, and there is currently a lack of momentum for climate change measures. In response to this issue, JCLP has decided to establish the "Day to End the Too Hot Summer" during this hottest time of the year, creating a social impetus to reframe "heat" as a climate change issue. This memorial day aims to share the commitment to halt the climate crisis for future generations and serve as a starting point for advancing the systemic transformation of society as a whole.

Are you making progress on measures for the "2024 Problem"? With stricter management of drivers' working hours, reducing "waiting time" has become an urgent issue in the logistics field. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability situation, reducing unnecessary waiting and queueing, and shortening waiting times to alleviate the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start addressing the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult with us.
