WebThis works both ways, say 10 similar machines in a room produce 100 dBA then removing one machine completely will only reduce the overall noise level to 0.5 dBA, you would need to silence or remove 50% of the machines to achieve a 3 dB reduction. See also our dB page for more details on adding and subtracting decibels - Leq Calculation.

WebJun 12, 2015 · Measured with dBA, that would be something like 65dB. Now, take a dBZ value of 95dB, this time from a single tone at 1000Hz. If measured with dBA, then it will also be 95dB. So, the sound level depends on the frequencies, and when all you have is the sound level you don't know which frequencies were present when the reading was made. http://www.comairrotron.com/important-factors-consider-when-comparing-acoustical-data?language=en WebUse this calculation program to get a very approximate idea of the equivalent sound level produced by the machines on a sensitive spot.
