Below is from the Hyperacusis Research website: Hyperacusis patients in the US, UK, and Canada: Would you be interested in testing a hybrid in-ear device for hyperacusis? We are helping a researcher gauge interest in testing such a device, which would reduce loud sounds, allow normal sounds through, and include built-in noise generators for sound therapy. The goal would be to slowly transition patients from sound attenuation to sound enrichment. The 2-minute survey is on our main website, hyperacusisresearch.org -- the first item under the "manage noise" tab, labeled "hyperacusis device."
