audiogram

The horizontal axis of the audiogram indicates the frequency of the sound (Hz), commonly known as tone. The ordinate indicates the intensity of the sound. Decibel (dB) is used to indicate that the audiogram is the most direct basis for hearing aid fitting and understanding of hearing conditions. Understanding the audiogram can help us understand the hearing loss. With audiometry, when used, the main part of the instrument automatically provides various frequency stimuli from weak to strong, automatically changing the frequency, and the subject wears a closed-air-proof earphone when listening to the test. When the sound is heard, the button can be used. According to the test reaction, the audibility curve is directly drawn, which is the audiogram. Basic Information Specialist Category: Otolaryngology Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Before taboo: clean your ears. Normal value Normal people's hearing range is between 0 and 25 decibels (dB). Clinical significance abnormal situation: Mild hearing loss is 26 to 40 dB. In this case, the patient does not or only feels a slight hearing loss and generally does not affect verbal communication skills. Moderate hearing loss is 41 to 55 dB. The patient feels that the hearing is declining, and when the speech is exchanged, the other party needs to repeat or slightly raise the sound to hear clearly. Moderate to severe hearing loss 56 to 70 dB. The hearing loss is very obvious. When you talk, you need to speak loudly to hear clearly. Severe hearing loss is 71 to 90 dB. In the dialogue, you need to shout loudly, and you can understand the meaning of the speaker by looking at the other person's mouth shape. Extremely severe hearing loss >91dB. In the case of long-term severe hearing loss in both ears, in addition to severe hearing loss, the patient's speaking teeth will be unclear. Patients with hearing impairment in the population need to be examined. High results may be diseases: conductive deafness, brain sounds Taboo before inspection: Wash your ears. Taboo when checking: 1. Conduct in a quiet environment. 2. The subject is doing well, don't move. Inspection process With audiometry, when used, the main part of the instrument automatically provides various frequency stimuli from weak to strong, automatically changing the frequency, and the subject wears a closed-air-proof earphone when listening to the test. When the sound is heard, the button can be used. According to the test reaction, the audibility curve is directly drawn, which is the audiogram.
