Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We expect the group of volunteers exposed to recreational noise who used hearing protectors to exhibit less or no temporary shift in their auditory threshold compared to the group that did not use hearing protectors | — |
Secondary
| Measure | Time frame |
|---|---|
| We expect that volunteers exposed to recreational noise who used hearing protection will report no auditory complaints or fewer complaints than the group that did not use protection. Symptoms include, for example, tinnitus, a sensation of fullness in the ear, hypersensitivity to sounds, difficulty understanding speech in noisy environments, and a subjective perception of hearing changes | — |
