An earplug () for selective attenuation of sound has a body with at least one sound path. An insert () is housed in the body (), which has at least one sound passage with an acoustic filter. The acoustic filter is configured to provide a specific frequency response and thus a determined attenuation of sound passing through the earplug. Means () is arranged at a top surface adapted to activate or deactivate the sound path. Each acoustic filter comprises an upper acoustic port (), at least one acoustic mesh () and/or acoustic membrane (), an acoustic chamber () and a lower acoustic port (). An insert () with an acoustic filter for selective attenuation of sound is provided for use in an earplug.

A shaped component made of technical fabric for protection of the speakers of electronic devices with waterproofing characteristics of IPx7 degree or higher, which have water-tight speakers. In addition to the function of protection from solid particles, the invention is optimised for guaranteeing fast and efficient draining-off of the water that has penetrated into the water-tight speaker so as to recover as fast as possible the initial acoustic functionality, in an improved way as compared to the solutions currently available. The component according to the present invention comprises within it one or more openings covered by synthetic technical fabric with hydrophilic treatment, to guarantee rapid exit of the water that has entered the speaker module, and one or more openings covered by synthetic technical fabric with hydrophobic treatment, to favour entry of air into the volume in front of the speaker, thus ensuring proper emptying thereof. In detail, among the various possible embodiments, the present invention may be implemented as a multilayer die-cut part that combines a hydrophilic synthetic fabric with a hydrophobic synthetic fabric and with one or more layers of adhesive to enable assembly inside the end products.
