Ear defenders with double damping technology. The headband eliminates the problem of excessive pressure on the head and enables comfortable work with a helmet. The use of double damping technology, despite the slight pressure on the head offered by the headband, results in a very high parameter of reducing the intensity of surrounding sounds.
- damping effectiveness: SNR 31 dB
- headband made of stainless steel wire with four-point mounting
- soft and wide sealing cushions, well-fitting to the head, made of skin-friendly materials
- weight: 250 g
Cushion dimensions:
- dimension A: about 40 mm
- dimension B: about 65 mm
How to choose ear defenders for the workplace:
Protective ear defenders provide protection for the operator against harmful noise by reducing the noise level measured in decibels by the value of the SNR parameter. The upper limit for an 8-hour workday has been set at 85 dB. If the average noise measurements in the workplace exceed this value, then ear defenders with an SNR parameter that allows reducing the noise level to 85 dB or less should be used. Assuming that we will work all the time with ear defenders with an SNR parameter of 32 in an environment with a noise intensity of 116 dB, then we will reduce the noise to 84 dB.
If the operator wears ear defenders for longer than a few minutes, it is worth paying more attention to structural elements that improve their comfort. Appropriately wide sealing cushions made of skin-friendly materials should accommodate the entire user's pinna. The soft padding of the headband will relieve pressure on the top of the head. The force with which the ear defenders adhere to the head affects not only comfort but also damping effectiveness, so for continuous work, it is worth choosing ear defenders with not necessarily the highest available, but properly selected SNR parameter.
