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.

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.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

We have introduced Majesta Fragrance to a nightclub in Yokosuka City, Kanagawa Prefecture, creating a fragrant atmosphere throughout the floor. The model we have introduced is the "MF-02S," which costs 8,800 yen per month (tax included). The scent you have chosen this time is "Sabon," a high-quality soap fragrance reminiscent of luxury hotel amenities. Its clean and transparent refreshing scent spreads throughout the entire floor, warmly welcoming customers who visit. By introducing scent design to the nightclub, we can enhance the extraordinary experience and create a memorable space that lingers not only visually but also through "scent." Majesta Fragrance offers a rental service for commercial aroma diffusers, and we also provide a free trial installation. If you are interested in scent design, please feel free to contact us.

In the July 8, 2026 issue of Air Conditioning Times, we featured "Flex Chamber" and "SS Premier" in a duct special.

SS Premier has won an award at the 24th Environmental and Equipment Design Awards. This award is organized by the General Incorporated Association of Architectural Equipment Comprehensive Association and recognizes outstanding efforts in environmental and equipment design. We will continue to strive for further improvements in quality and technology.
