Noise reduction from an 85 decibel compressor
« on: January 05, 2009, 08:56:53 PM »
We have a compressor giving out 85 decibels which is to be moved outside at our golf club. The noise level needs to be reduced as much as posible so I am building a small (1200mm x 900mm x 1000mm) enclosure using dense concrete blocks and based on concrete paving slabs, how can I reduce the noise further.

You can line the enclosure with our SSP Foam Mat 1" or thicker, you need to fully enclose this generator but you will need air flow so you must create a baffle system with atleast 3 or more 90 degree turns per baffle system for both intake and exhaust...this to must be lined with SSP foam Mat.

Sound absorbing fire retardant acoustic foamdesigned to reduce reverberation and airborne noise. Ideal for small enclosures and machinery covers.Fire Retardant Acoustic Foam is totally non-flammable. It can be used in the same way as ordinary acoustic foam but is far more versatile. It is of particular use in heating and ventilation ducts, machinery guards and enclosures and even buildings. It also offers good thermal insulation and has the advantage over other types of insulation of not losing dust or fibre particles.

I dropped my compressor by about 10db by building a box around it and covering the inside with home depot foam board.  It used to feel like it was drilling holes in my brain, and now i can talk normally, or hear the radio with it running.

Nice Job! ;D 
If you want to increase that db drop then replace the home depot foam with SSP foam mat that carries 25 STC and NRC .30

Thanks for the post! its nice to see when people reply with results.
