The decibel noise level of a concrete breaker is at around 111 to 113. This can vary depending on what concrete breaker one is using, and might have a different noise level.

Yes, it's not how to reduce roots blower noise level, it's how to reduce turbo blower noise level. Normally turbo blower noise level is less than 80 dba when roots blower noise level is more than 90 dba, some user are still not satisfied, they want the noise level below 60 dba or even 50 dba.

Sound level is measured in decibels (dB) by a sound pressure level meter (SPL meter).There isn't really a specific level at which "sound" becomes "noise." "Noise" is a somewhat subjective term for "sound that I do not want to hear"; for example, if rap music is at all audible, I personally consider it "noise" though my son does not.In signal processing, "noise" means "anything that is not a deliberate signal" and generally has a significantly lowerdB level than the signal does.
