Six checks decide whether an earplug suits someone who finds certain everyday sounds hard to sit with: attenuation, fit and occlusion, material, discretion, cost per use and when to take them out. Here is how each one measures up, with real numbers.

Most misophonia trigger sounds are quiet, roughly 40–65 dB at 1 metre. Here is the frequency band and level of each common one, and what a passive SNR 24 earplug does to it, octave by octave.

Trigger sounds are reported more often by adults with ADHD or autism, but the link is an association, not a cause. Here is what the research shows, how misophonia differs from sensory overload, and what helps in each case.

Your own chewing gets louder with earplugs in because the seal traps sound that travels through your jaw and skull. Here is how depth, tip shape and the right size make it smaller, and when to simply take them out.

Misophonia often begins in childhood or the early teens, and the family table is usually where it shows first. Here is how UK parents can plan meals, siblings, school support and exams, and which earplug suits which age.

Passive earplugs, noise cancelling headphones and masking audio each handle a crunch, a click and a drone differently. Here is which one suits the shared table, the desk, the library, the train and home.

Foam blocks the most sound but makes your own chewing louder inside your head, while reusable silicone leaves the room quieter but present. Here is how foam, silicone, wax and custom-moulded earplugs compare when certain sounds bother you.

Researchers and clinicians use a handful of validated misophonia questionnaires, from the 6-item Amsterdam scale to the 86-item Duke questionnaire. Here is what each one measures, who uses it, and why a score describes burden rather than giving a diagnosis.
