hörseltröskeln

Hörseltröskeln is a Swedish term that translates to "hearing threshold" in English. It refers to the lowest intensity of sound that a person can detect at a given frequency. This threshold is a fundamental measure in audiology and is used to assess an individual's hearing ability.

The hearing threshold is typically measured in decibels (dB). A lower decibel value indicates better hearing, as it means a quieter sound can be perceived. Conversely, a higher decibel value signifies poorer hearing, as louder sounds are required for detection. The hearing threshold varies across different frequencies, with humans generally being most sensitive to sounds in the mid-frequency range (around 1,000 to 4,000 Hz).

Audiograms, which are graphical representations of hearing ability, plot the hearing threshold at various frequencies. These charts are crucial for diagnosing hearing loss and determining its type and severity. Factors such as age, noise exposure, and certain medical conditions can affect an individual's hearing threshold. Understanding the hearing threshold is essential for evaluating hearing health and implementing appropriate interventions.
