Bucket Crusher and Mobile Crusher Noise / Sound Levels

Bucket Crusher and Mobile Crusher Noise  / Sound Levels

There are a great many sites titled "crusher sound levels" or "bucket crusher noise" which do not publish figures of decibel levels.

I have come across this HSE document (governmental body) which one would hope is reliable. The document is "Control of Noise in Quarries".

The document lists various sound / noise level for static / fixed and mobile crushers in decibels / dBA / db. For a bucket crusher I used figures listed for a mobile crusher platform, as they are likley to be closer match in terms of size.

You will note the table also includes way to reduce noise for the operator. However, the document is not aim at environmental noise reduction.
