In general, a high risk of hearing loss has been known if you continue to hear the sounds of a high acoustic pressure level, such as listening of the portable audio and working with too loud noises. This app allows you to check your hearing characteristics by finding the gain point of smallest audible tone for each frequency. The results are displayed in easy-to-read charts like the audiogram. Please try to consider the wellness of your ears and and your natural hearing by knowing your current hearing status. Features: - Test frequency: 125, 250, 500, 1000, 2000, 4000, 8000, 12000 (Hz) - Test tone type: Intermittent signal (Tone A) / Continuous signal (Tone B) - Test tone output: Left / Right - Result graph display (Graph): Frequency response of hearing with ATH (*1) compensation. - Reset graph display (Reset) *1: ATH (Absolute Threshold of Hearing) ATH is also known as the hearing threshold, and is the minimum sound pressure level of pure tone that can be detected on the hearing in noise-free environment. Human is said to be able to listen from 20 Hz to 20000 Hz, but the sensitivity of the hearing will vary greatly depending on frequency. ATH varies with age and sex, but is a good sensitivity at mid range (1000 Hz - 5000 Hz), and needs more greater sound pressure level at a lower and higher frequency. Note: Before the diagnosis start, please set the hardware volume control to the central position of 50%. As you tap the volume stepper "+", the volume of the test tone will have more gain. Adjust carefully to avoid excessive volume for your ears. We recommend the use of genuine Apple earphones for the hearing test. Remarks: We hope that you keep to have an interest on a daily basis to the wellness of hearing by this app. If you feel the need to health management of ear, it is recommended to visit the medical specialist.
