Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Between the ages of 18 and 65
Have bilateral, symmetric sensorineural hearing loss that is less than 75 decibels (dB) Hearing Level (HL) at 1000 Hz and below.
Must not have
Subjects who are not native speakers of English.

Summary
This trial is testing special computer programs in a wearable device to help people who use hearing aids understand speech better. The device adjusts sound volume based on how loud the sounds are, making it easier to hear quiet sounds without making loud sounds too loud.
Who is the study for?
This trial is for English-speaking adults aged 18-65 with bilateral, symmetric sensorineural hearing loss that's less than 75 dB at low frequencies. It excludes non-native English speakers, those with normal or mixed hearing loss, asymmetric hearing loss, and severe loss above 70 dB at higher frequencies.
What is being tested?
The study tests the Tympan device to see how its nonlinear signal processing algorithms affect speech understanding in people with certain types of hearing loss.
What are the potential side effects?
Since this trial involves a non-invasive device designed to improve speech perception, side effects are minimal but may include discomfort from wearing the device.

Other Research
Common treatments for sensorineural hearing loss (SNHL) include hearing aids, cochlear implants, and auditory processing technologies like nonlinear signal processing algorithms. Hearing aids amplify sound to make it more accessible to damaged auditory pathways.
Cochlear implants bypass damaged hair cells in the cochlea, directly stimulating the auditory nerve. Nonlinear signal processing algorithms enhance speech perception by selectively amplifying speech signals while reducing background noise.
These mechanisms are crucial for SNHL patients as they improve the clarity and intelligibility of sounds, thereby enhancing communication abilities and overall quality of life.
