Digital Audiometer vs. Conventional Audiometer (Gold Standard): Study of Tonal and Vocal Recognition Thresholds

Centre Hospitalier le Mans52 enrolled

Overview

According to the WHO (February 2, 2024): More than 5% of the world's population, or 430 million people (including 34 million children), need rehabilitation services due to disabling hearing loss. It is estimated that 700 million people will be affected by 2050, or one in 10 people. It is estimated that by 2050, nearly 2.5 billion people will have some degree of hearing loss. In most cases, audiometric testing involves determining the patient's tonal thresholds and speech recognition thresholds. The Hearing Space device is a digital audiometer that can perform both tonal and speech audiometry. This device stands out because it allows users to calibrate its transducers themselves via a guided, automated procedure. This procedure ensures that the calibration complies with the relevant calibration standards.

Outcomes

Primary Outcomes

auditory threshold levels and speech recognition thresholds

Measurements of pure-tone audiometric thresholds and speech recognition thresholds will be taken for each of the patient's ears using the Hearing Space digital audiometer and the Interacoustic AC40 physical audiometer (in random order). The results obtained will then be statistically compared to determine whether or not there is a significant difference between the results obtained by the two devices.

Time frame: From inclusion to the end of the intervention (40 minutes on average)
