The hearing threshold for low-frequency tones of 10-160 Hz was measured in a pressure field to investigate the effects of aging on hearing sensitivity. Participants were young adults of 19-25 years old and older adults of 60 years and over. Measurement results showed that the older listeners had a higher threshold than the young listeners on average. However, the difference of median thresholds between these two groups was 5-10 dB at every measurement frequency, which was a much smaller difference than that observed for high-frequency tones around 2,000 Hz and above. Comparison of the low-frequency thresholds and audiograms of the listeners indicated almost no correlation between these two. These experimental results suggest that older people retain good hearing sensitivity in the low-frequency region compared to their degraded sensitivity at higher frequencies. The second report of the study presented at Low Frequency 2006 in Bristol, UK: the number of participants was increased.
