If an individual has a low frequency hearing loss, which additional frequencies should be tested?

In the case of a low frequency hearing loss, testing additional frequencies is crucial to comprehensively assess the individual's hearing ability and to understand the full extent of the hearing loss. Low frequency hearing loss typically refers to difficulties in hearing sound frequencies that are lower than those in the mid and high ranges, usually defined as below 500 Hz.

Both 125 Hz and 250 Hz are standard frequencies that fall within the low frequency range. Testing at these frequencies provides valuable information regarding the patient's auditory function and can help in the identification of specific hearing issues, such as conductive hearing loss or particular types of sensorineural loss.

By including both frequencies in the assessment, audiologists can obtain a clearer picture of the individual's hearing profile, which is vital for accurate diagnosis and effective management. In short, thorough evaluation at 125 Hz and 250 Hz helps to ensure that any low frequency hearing loss is fully characterized, supporting the development of appropriate treatment plans.
