Preliminary field testing has shown a max reduction of 13dBA when measured at an 8 metre distance from the rock breaker. Although there are many different types of rock breakers available, we are seeing a 7-13 dB reduction when using our RW27 Hushtec custom-fitted attachment ,which is a very noticeable change in SPL to the human ear.
