## How old do you have to be to have normal hearing?

Figure 1. Median audiograms from ISO 7029 for males (top) and females (bottom) 30, 40, 50, 60, 70, and 80 years of age.5 Also shown in red are the previous WHO boundaries for hearing loss (top panel) and the current revised boundaries (bottom panel).

## What’s the normal hearing rate for a 70 year old?

If one calculates the WHO hearing-impairment grade using the four-frequency pure-tone average (PTA4), assuming the audiograms shown represent the better ear, those for men and women 30, 40, 50, 60, and 70 years of age would all be labeled “normal”!

What is the correlation between hearing and age?

As noted in the lower right corner of the top panel, however, there is a moderate correlation (r=0.61) between better-ear PTA4 and the perceived difficulties as measured by the HHIE-S. When age is controlled via a partial correlation, the partial r (r p) increases slightly to 0.69.

When does disabling hearing loss begin in who?

Importantly, the WHO hearing-impairment grading systems not only quantify the severity of the hearing loss from the pure-tone audiogram as described above, they also maintained that “disabling” hearing impairment does not begin until the severity has reached the “moderate” level.

### Is it common for older people to have hearing loss?

Hearing loss that occurs gradually as you age (presbycusis) is common. Almost half the people in the United States older than age 65 have some degree of hearing loss. Hearing loss is defined as one of three types:
