When should interoctave frequencies be used on an audiogram?

Interoctave frequencies should be utilized on an audiogram when there is a significant gap of 20 decibels between the octaves. This practice is important because the use of interoctave frequencies allows for a more precise assessment of a patient's hearing capabilities, especially in cases where there are steeply sloping audiometric configurations or specific frequencies that exhibit considerable hearing loss. By including interoctave frequencies, audiologists can identify areas of hearing loss that may not be accurately represented if only the standard octave frequencies are measured. This enables a better understanding of the patient's overall audiological profile and more tailored recommendations for treatment or hearing aids.
