Ear pads or CLAW earplugs are ideal for bikers. A large number of motorcyclists have an annoying ringing or noise in their ears after a long ride that just doesn't stop. This is mainly due to wind noise under the helmet. If this happens frequently, permanent hearing loss may occur or the whistling may not go away at all.
The higher the SNR, the quieter the volume. The SNR value is a simplified average. Earplugs dampen low tones differently than high tones. To find out, you need to compare the plugs at different frequencies and the corresponding H, M and L values.
H: High frequencies between 2000 and 8000 Hz M: Medium frequencies between 1000 and 2000 Hz L: Low frequencies between 63 and 1000 Hz
