Objectives
Narrative objectives1
In conversational listening, signals from the inner ear from the left and right ear are rapidly processed in the auditory nerve circuit to extract and understand the necessary directional information and conversation information from coexisting environmental sounds (noise), and memory and cognitive functions such as attention to conversation information and retention of a series of information also play an important role. The directional sense of sound processed by the central auditory system is based on the separation and synthesis of signals from the left and right hemispheres, and plays an important role in daily life. The cocktail party effect The directional sense is also useful in the diagnosis of posterior labyrinthine disorder (a central disorder), because the difference in time and intensity between the two ears is produced by the direction of the sound source, with the difference in time playing an important role at low frequencies and the difference in intensity at high frequencies becoming clearer due to the shading effect of the cranium.
The phenomenon of an increase in the auditory range value (decrease in hearing acuity) with age, especially at high frequencies, is well known as senile hearing loss. In addition to this, elderly people characteristically complain of a strong decrease in their ability to hear speech, such as "I can hear sounds but cannot understand what is being said" or "I cannot hear in noisy environments. In addition to an elevated auditory threshold due to peripheral auditory dysfunction, central auditory processing may be impaired. This is thought to make it more difficult to retain and comprehend information. In recent years, the use of cochlear implants for hearing loss has progressed, and it is now possible to improve hearing in patients with severe hearing loss, whereas previously it was impossible to intervene.

Basic objectives -Others
In this study, with the aim of evaluating the central circuits that process directional perception in particular, we developed a left-right, single-syllable listening test in noise, a long-sentence listening test, event-related potentials to measure auditory perception in the center, and DPOAE (DPOAE in the high frequency domain), a method to evaluate detailed inner ear function other sensory evaluation.

Assessment
Primary outcomes
In addition to analyzing normal values by age for each newly developed test, correlations between tests, etc. will also be analyzed. Since this is not a clinical trial to demonstrate the efficacy of therapeutic actions, there will be no primary endpoint.
