Acoustic characteristics in hard of hearing individuals?

Hard of hearing individuals often exhibit distinct acoustic characteristics, such as reduced sensitivity to certain frequencies, particularly in the higher range. This can result in difficulty distinguishing between similar sounds, leading to challenges in speech perception. Additionally, they may experience a phenomenon known as "recruitment," where loud sounds are perceived as disproportionately loud, making it harder to tolerate background noise. Overall, these acoustic characteristics can significantly impact communication and social interactions.
