[Case Study] Aluminum Fiber Sound Absorption Panel Poal [Soundproof Enclosure]

basic information

◆Case Study of Waste Treatment and Recycling Operators The noise generated by the crushing machines for home appliances exceeded 100dB, making communication between workers impossible. Measurements of the sound sources revealed that the noise from the mill part of the crusher, the area around the feed opening, and the sound from the sorting machine's exit, along with echoes from the walls, were particularly loud. By covering the crusher with soundproof enclosures made of Poal and installing sound-absorbing panels on the nearby walls, we achieved a significant noise reduction from approximately 105dB to about 87dB. 'Poal' can be easily bent and punched, allowing it to be processed into shapes that fit the site. *105dB is comparable to the sound of a car horn from close range, while 87dB is similar to the noise level inside a crowded train. ◆Case Study of a Major Construction Company 'Poal' was adopted as the material for soundproof walls used in construction projects. When a soundproof wall approximately 60cm high is installed on top of a 3m high soundproof enclosure, it achieves a noise reduction effect equivalent to that of a 6m high soundproof enclosure (note). Since the height of the soundproof enclosure can be kept lower, it creates less sense of pressure on the surroundings and is easier to install. 'Poal', being thin, lightweight, and highly weather-resistant, does not suffer from performance degradation due to water absorption, making it ideal for outdoor use.

Detailed information

• 

  Sound absorption rate data This is data on sound absorption rates measured using the reverberation room method by a public institution.

• 

  Soundproof wall for construction work. By installing it on top of the conventional soundproof enclosure, the height of the enclosure can be reduced.

• 

  Recycling operator before construction Before using the poal, the crusher was exposed. Noise levels exceeded 100 dB.

• 

  Recycling business operators, after construction A cover was installed over the motor part of the crusher using Poal. By enclosing it with steel plates and placing sound-absorbing material inside, and also installing sound-absorbing covers at the product discharge opening, we aimed to achieve both noise reduction and operability. As such, processing tailored to the shape of the machine is possible. Poal is heat-resistant and safe to use near motors, engines, generators, etc.
