Noise Measurement and Noise Prediction Simulation

  • Environment & Energy Conservation
  • Design

From visualizing noise conditions to proposing noise measures

We determine the source and intensity of noise, assess its impact on the surrounding area through measurements or simulations, and provide support in preparing measures to meet regulatory requirements or addressing noise complaints.

Process and description of noise measure study service

Example of noise control measures

  • Noise conditions before measures 　
    Noise barriers (concrete walls/acoustic absorbers) applied to air-conditioning equipment on the roof. 　
    →The maximum level of noise predicted at property boundaries reached 59 dB.
  • Noise control measures 　
    (1) Acoustic absorbing panels applied to existing noise barriers. (2) Silencers placed on the upper part of the air-conditioning equipment. (3) Silencers applied to ventilation holes. 　
    →The maximum level of noise at the property boundaries was reduced to 48 dB, an approx. 10 dB reduction.
