According to the National Institute on Deafness and Other Communications Disorders, you may have hearing loss if you experience three or more of these symptoms:

- You have problems hearing over the telephone.
- You have trouble following the conversation when two or more people talk at the same time.
- People often complain that you turn up the volume too high on the television or radio.
- You have to strain to understand conversation.
- You have trouble hearing when there's lots of background noise.
- You often find yourself asking people to repeat themselves.
- Many people you talk to seem to mumble or speak unclearly.
- You misunderstand what others are saying and respond inappropriately.
- You have trouble understanding the speech of women and children. - Women and children typically speak in higher frequencies, which often are the first frequencies to be affected by noise-induced hearing loss.
