According to industrial safety law, areas subject to hazardous noise must be clearly defined, and workers notifies of the danger. In many cases, the noise hazard is intermittent and that’s precisely the situation for which the GA902 and GA904 were designed.

The GA902 activates only when the noise exceeds a pre-set level allowing exposed workers to wear ear defenders - often a less than popular safety measure - only when absolutely necessary.

dBAlert! activates only when the noise exceeds a pre-set level, warning exposed workers that noise levels have become dangerous and to put on their ear-defenders. Perhaps more importantly for the employee, this means that they will also know when they can legally take them off!
