For example, the median hearing loss at 500 Hz for a normal 70-year-old man is 8 dBHL according to the ISO 7029 standard with a positive standard deviation of 10 dBHL. A hearing loss of 25 dBHL can be expressed as 1.7 standard deviations (25 dBHL/10 dBHL) above the median and this corresponds to the ninety-sixth percentile (or P96).
