What is the purpose of threshold determination in hearing assessments?

The purpose of threshold determination in hearing assessments primarily focuses on establishing the intensity level at which a patient can detect sounds. This measurement provides crucial information about the patient's hearing sensitivity across different frequencies. By identifying the softest sounds that the patient can hear at various pitches, hearing professionals gain insight into the degree and configuration of the hearing loss. This data serves as a foundation for further evaluation and fitting of hearing aids, ensuring that devices can be adjusted to meet the specific amplification needs of the individual.

When conducting threshold determination, clinicians often utilize pure tone audiometry, which systematically tests each ear at various frequencies to find the minimum audible level for the patient. This ensures that any prescribed interventions, such as hearing aids, are tailored to address the specific auditory deficits that have been identified during the testing process.
