What is the impact of stiffening effect in terms of frequency?

The stiffening effect primarily influences the hearing sensitivity in low frequencies. This phenomenon occurs when the structures of the cochlea and the surrounding tissue become stiffer, which typically leads to a decrease in sound transmission at lower frequencies. The cochlea is designed to respond optimally to a wide range of frequencies, but when it experiences stiffness, it can affect how sound waves in the lower range are processed, resulting in conductive hearing loss characteristics at those frequencies.

In normal hearing, the lower frequencies are usually detected easily, but the stiffening effect can reduce the sensitivity of a person's hearing in this range, making sounds appear quieter. This is often seen in conditions such as otosclerosis. Understanding this is crucial for audiologists and hearing aid dispensers, as it can help guide treatment and recommend appropriate amplification strategies for individuals affected by this phenomenon.
