In this study, we used the Profile of Hearing Aid Benefit to access 134 patients' perceived benefit with a variety of linear hearing aids, some more capable than others at achieving prescribed frequency gain targets. We also sought to explore various audiologic and subject factors that might ...
Maximum high frequency hearing loss (≥3 kHz) may be 90 dB (Fig. 20). Maximum low-frequency hearing loss should be no more than 30 dB at 0.5 kHz. In addition, the slope of hearing loss between 0.5 and 2 kHz should be 30 dB or more. The difference between the two ears should be...
Equally important is the frequency of your hearing loss. You’ll need to choose a hearing aid that targets the frequencies you have trouble comprehending. Functionality is an important consideration. With so many available features, you’ll need to decide which ones matter most to you. Popular...
It is postulated that the frequency response should be flat up to a given frequency, the audiogram's cut 掳ff frequency, and thereafter should rise with a variable slope to a certain level (treble amplification), slope and treble amplification being functions of input sound pressure level. Ten...

This is because walking activity requires minimum walking frequency and duration as requirements for walking activity regardless of walking intensity. We found significant associations between walking initiated in midlife, but not late life, and cognitive performance. This is consistent with a previous ...
The results are charted on an audiogram, a graph that shows the type, degree and configuration of your hearing loss by comparing pitch (frequency) with loudness (intensity). The pattern recorded will help your audiologist determine your hearing threshold. Bone Conduction Testing Bone conduction ...
