puhtaanääniaudiometrialla

Puhtaanääniaudiometria, known in English as pure-tone audiometry, is a fundamental audiological test used to measure an individual's hearing thresholds for different frequencies. It is a non-invasive diagnostic tool that determines the quietest sound a person can hear at various pitches. The test is typically conducted in a sound-treated booth to minimize external noise interference.

During a puhtaanääniaudiometria, the patient wears headphones. A series of pure tones, each at a specific frequency, are presented at varying intensities. The patient's task is to indicate when they can hear the tone, usually by raising their hand or pressing a button. The audiologist then records the lowest intensity at which the patient can detect the sound for each frequency. This data is plotted on an audiogram, a graph that visually represents hearing ability across the frequency spectrum.

The results of puhtaanääniaudiometria are crucial for diagnosing hearing loss, determining its type (conductive, sensorineural, or mixed), and assessing its severity. This information guides the selection of appropriate interventions, such as hearing aids or other assistive listening devices, and informs treatment plans. It is a standard procedure in audiology clinics and is often part of routine hearing screenings.
