EN 352-1:2002 – Hearing Protectors – Ear muffs

Ear muffs tested in accordance with EN 352-1:2002 must be labelled with the standard number, manufacturer and model identification. Where required, there should also be indication for the orientation of the ear muff e.g. ‘TOP’ and/or ‘LEFT’ and ‘RIGHT’.

Materials and construction

Any materials used to make the product that will come into contact with the skin must be non-staining and not likely to cause skin irritation, allergic reaction or other adverse effects on health. The device must be free from sharp edges to be considered safe for use, and cleaning and disinfection methods specified should not cause damage or impairment to the hearing protection.

Size and adjustability

This is tested to ensure that ear defenders are suitable for the range of head sizes designated by the manufacturer. With EN 352-1:2002 compliant products you should expect an adequate fit.

Cup rotation

Hearing protectors are measured to assess whether or not the rotation of the cups is sufficient. There must be enough rotation for wearers to adjust the device to achieve the best fit.

Headband force

There should be no excessive force on the wearer’s head.

Cushion pressure

There should be no excessive pressure on the wearer’s head.

Resistance to damage when dropped

For this test, the ear protection product is dropped from a specified height onto a solid steel plate. If part of the product cracks or breaks then it will fail the test.

Change in headband force

After the tests above have been completed, headbands are subjected to flexing for 1000 cycles, before being conditioned in a water bath at 50°C for 24 hours. Once complete the headband force is measured a second time. A maximum deviation between the 2 measurements determines whether it passes.

Resistance to leakage

This is specifically for ear muffs with fluid-filled cushions. A vertical load of 28±1 Newtons is applied to the cushion for 15 minutes and any leakage caused will constitute a test failure.

Ignitability

A steel rod heated to around 650°C is applied to the hearing protection device. If any part ignites or continues to glow after the removal of the rod then the device will fail the ignition test.

Minimum attenuation

The minimum attenuation value must be recorded for EN 352-1 compliant ear muffs. This is the lowest sound pressure level perceivable by the ear of 16 human test subjects with and without the hearing protection worn. It is then possible to calculate the performance of the model from these values.

Here are the SNRs required to remain compliant at various noise levels: (noise calculator here)

The higher the SNR level, the more protection the product gives.

Noise Level Minimum SNR Ideal SNR Maximum SNR
85 dB 5 9 – 14 18
90 dB 10 14 – 19 23
95 dB 15 19 – 24 28
100 dB 20 24 – 29 33
105 dB 25 29 – 34 38
110 dB 30 34 – 39 43
