Acoustic Accessibility

An emerging framing of accessibility that considers a user's full acoustic environment - which sounds reach them, how loud, and in what mix - as a design surface to be adapted to individual sensory needs rather than treated as fixed background. While hearing accessibility has historically focused on amplifying sound for d/Deaf and hard-of-hearing users, acoustic accessibility extends to users with noise sensitivity, misophonia, hyperacusis, autism, ADHD, and PTSD who need selective suppression, soundscape personalization, or context-aware filtering. The concept emphasizes giving users fine-grained control over their auditory world rather than offering binary mute/unmute choices, and treats sounds as individually negotiable rather than as a single environmental stream.
