Constructions zones can be hotbeds for unbearable noise. Prolonged exposure to the sounds of angle grinders, pneumatic hammers and other loud equipment can seriously affect construction workers hearing. The Royal National Institute for Deaf People recommends wearing ear defenders if sound levels are consistently about 85dB. However, if you are an employer, you should be considering providing ear protection when noise levels reach 80dB. You can find high-performance ear defenders tested to CE EN352-1 standards at Builder Depot.
