Noise source investigation

Noise source investigation

We have prepared two devices to explore the source of sound! The "acoustic camera" visualizes sound in a thermographic way!

Nanyang Wood Co., Ltd. conducts "Noise Source Surveys." We have two devices prepared to investigate the source of sound: a digital sound level meter and a visualization device using an acoustic camera, both of which help identify the location of the sound. With the digital sound level meter, measurements can be taken from 30 dB to 130 dB. Measurements can be taken in seconds, and the data can be graphed to show the fluctuations in noise levels. Additionally, measurements using the visualization acoustic camera not only identify the location of the noise but also allow for measurements of the surrounding space, enabling pinpoint confirmation of where the sound is coming from and the range of sound that can be heard. [Features] <Measurements with the Digital Sound Level Meter> ■ Measures noise levels in dB (decibels) ■ Capable of measuring from 30 dB to 130 dB ■ Measurements can be taken in seconds, and the data can be graphed to show fluctuations in noise levels *For more details, please refer to the related links or feel free to contact us.

We are currently offering a sample report of the "Attic Earthquake Risk Assessment Survey"!

We are currently offering a sample report of the "Attic Earthquake Risk Assessment Survey"!

Are the measures against the risk of ceiling collapse or falling debris in the building sufficient? There is a risk of evacuation routes being blocked and potential human injury from falling objects.

The seismic standards for buildings in Japan are set high, but even if the building itself does not collapse, there is a risk that evacuation routes may be blocked due to the falling or collapsing of ceilings, making evacuation difficult and leading to potential human disasters. Therefore, measures to address these risks are also necessary. Our company conducts on-site inspections of building attics, focusing on panoramic photography, to evaluate earthquake risks and propose improvement measures. 【Report Contents】 1. Evaluation list of attic earthquake risk assessment survey results 2. Location map of attic earthquake risk assessment survey 3. Summary report of attic panoramic photography survey 4. DVD data of attic panoramic photography 5. Recommended diagram for attic seismic reinforcement measures 6. Related documents such as construction guidelines for attic reinforcement measures ★ We are currently offering a sample report of the "Attic Earthquake Risk Assessment Survey"! Please view it from the "PDF Download" link below.

[Example] Ecological Survey Using Drones Survey Work

[Example] Ecological Survey Using Drones Survey Work

Utilizing the advantages of drones to create maps based on data! Identifying habitats and population numbers.

This is an introduction to ecological surveys utilizing drones. The damage to agricultural products caused by wildlife has exceeded 20 billion yen annually. About 70% of this damage is caused by deer, boars, and monkeys, leading to a decrease in farming motivation and an increase in abandoned farmland. Therefore, we utilized the advantages of drones to conduct various surveys, including data acquisition through the use of thermal infrared cameras and aerial photography. Factors contributing to the expansion of wildlife damage include the expansion of wildlife habitats, a decrease in hunters leading to a reduction in capture numbers, and an increase in abandoned farmland. [Survey Examples] - Daytime: Confirming the situation around the flight path and creating automatic navigation routes - Nighttime: Manual flight based on the flight situation during automatic navigation - Infrared Camera: Capturing still images and videos, confirming transmitted images, and exploratory flights - Data Acquisition: Mapping based on data, identifying habitats and population numbers - Identification of resident animals and provision to local governments *For more details, please feel free to contact us.
