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.)

• Other construction services

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.

What do the members of the back office department consider when choosing or replacing a system? If the same product is handled by both a "manufacturer" and a "distributor," how do you feel about it? "Distributor"? Isn't it cheaper to buy directly from the manufacturer? It's obvious that receiving direct service is better, right? ...Is that really the case? In the materials we are releasing this time, we will explain the benefits of "introducing a distributor." Here’s a preview of the materials: 【If you’re going to choose, you should leverage the power of a distributor that handles the ○○ system!】 【Make the distributor your ○○○○○○○ and use them to the fullest!】 Along with these points, we are offering a "Distributor Evaluation Checklist" that will be your strong ally, free of charge! Please make good use of it.

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

In recent times, there has been a growing interest in infection control measures and facility hygiene management. Our company offers non-contact sensor products that are recommended for commercial facilities, food factories, and nursing and caregiving facilities. 【Sensors for Automatic Doors】 ● Light Touch Sensor HA-T401 … When you wave your hand in front of the automatic door, the sensor detects the movement and opens or closes the door. This is recommended for making doors with touch switches non-contact. ● Hand Wave Sensor PF-R5, PF-U2, DHS-1 … Opens and closes the automatic door by waving your hand in front of the sensor. ● Foot Switch PF-01S/01D/03S/05 … Opens and closes the automatic door by placing your foot in the opening. 【Access Control System】 ● Face Recognition + Unmanned Temperature Measurement DS Series … Allows for face recognition along with mask detection and body temperature measurement simultaneously. ● Automatic Disinfectant Spray Dispenser PHW-03B … Automatically sprays disinfectant when you wave your hand in front of the sensor. 【Nursing and Care Sensors】 ● Infrared Bed Exit Sensor "Just Place It Pole-kun" … This bed exit sensor is installed next to the bed and notifies via nurse call when the subject enters the detection range. ◎ For more details, please download the catalog or contact us.

In the latest "Age Estimation Evaluation Test" conducted by NIST, the AI facial recognition engine "FaceMe" ranked 5th in the world. 【What is the NIST FATE Age Estimation Evaluation Test?】 The NIST FATE Age Estimation Evaluation Test is one of the international benchmarks for facial analysis technology conducted by the National Institute of Standards and Technology (NIST) in the United States, which evaluates the age estimation accuracy of AI algorithms using a large-scale facial image dataset. 【Evaluation Results of FaceMe】 - World Ranking: 5th Among 20 vendors worldwide, FaceMe ranked 5th, demonstrating top-class accuracy in an international competitive environment. - Mean Absolute Error (MAE): 2.87 years FaceMe's average error in estimated age is 2.87 years, with only a 0.35-year difference from the top-ranked algorithm, achieving world-class accuracy. *MAE (Mean Absolute Error): A numerical representation of the error in estimated age (the smaller the number, the higher the accuracy). *NIST conducted the evaluation using 1 million facial images of individuals aged 18 to 30.

A new dedicated end cover that firmly protects the ends of the channel slit (N11/N112) has arrived! Just by installing it, you can prevent injuries and snags, significantly improving safety after construction. Furthermore, the finish is neat and beautiful. We offer three colors: chrome, white, and black.
