Cover Story: Hearing loss resulting from prolonged exposure to loud noise is known as noise-induced hearing loss (NIHL), and it often affects professionals exposed to occupational sources of high sound levels. The study aims to develop a new individual hearing protection device called the “dynamic earplug”, which protects from high-frequency noise and amplifies speech frequencies. Testing with the Fonix 7000 Hearing Aid Test System showed effective filtering of high frequencies (above 4000 Hz) from dental instruments and a speech frequency amplification of up to 13 dB (500 Hz–1000 Hz). The dynamic earplug shows promise as an efficient and comfortable hearing protection solution for professionals exposed to high-frequency noise. View this paper
