We always pay attention to the quality of sound but is even more important how we perceive it and what are the effects on our self. SoundReef is a biodegradable alternative to the common solution of PU foam plugs provided at concerts and festivals. By using biodegradable plastic from a solution of algae and water, it is possible to obtain a material with interesting sound-absorbing properties and capable of biodegrading at natural temperature.
With an average reduction of -18dB among frequencies, algae earplugs are able to cut out frequencies in an even way, reducing distortion of music while keeping the noise level in the safe range for our hearing.
