Comparison Stanley FatMax SFMEH230K vs Stanley STHM10K

The noise level produced by a demolition hammer during operation. The lower the noise, the more comfortable the instrument will be to use. However, it must be said that this parameter is quite approximate: the actual noise level depends on the specific mode of operation, the nozzle used, the material being processed, etc. Nevertheless, the indicators claimed in the characteristics make it quite possible to evaluate the overall “loudness” of the instrument – for example, in order to choose the appropriate noise protection means.

When evaluating the noise level, you need to keep in mind that the decibel is a non-linear quantity. Therefore, it is easiest to use comparative tables for evaluation. Here is a simplified version of a similar table for the noise range covered by modern demolition hammers:

75 dB — loud scream at a distance of 1 m;
80 dB — ringing of a mechanical alarm clock at a distance of 1 m;
85 dB — motorcycle engine with muffler in close proximity;
90 dB — freight car at a distance of 7 – 10 m;
95 dB — noise in the subway car on the stage;
100 dB — industrial shop;
105 dB — mid-range home theater at full volume.
