Hearing Test Tones starting from low to high. DO NOT LISTEN AT HIGH VOLUME. Each tone will play for 8 seconds. Turn speakers or headphones down to a low or comfortable level of hearing. These are the same tones used in Audiology testing. Young people can usually easily hear all the tones at a low volume. As age progresses, or with ear trauma, your hearing may become impaired. The loudness of the tones in this video does not change, only the pitch changes. If you find it hard or impossible to hear tones at a certain frequency range, you may have hearing loss. Only a trained Audiologist can do a proper diagnosis. This is only for entertainment and is not meant as a replacement for a True Audio-gram by a licensed Audiologist.
