At festivals or concerts, the volume is often so high that you can suffer hearing loss within as little as 15 seconds. Wearing the right hearing protection with the right noise reduction rating is important to prevent this. Sound waves can be categorised in three frequencies: high, middle and low frequencies. Alpine PartyPlug earplugs ensure an average noise reduction of 19 dB, guaranteeing perfect reduction of high, damaging tones while ensuring that music quality and speech comprehension remain optimal. Every pack contains a luxury travel pouch to store and transport the earplugs conveniently and safely.
