#How does the beep test work series

You will hear a series of two-syllable words at a volume that gradually decreases as the test progresses. To assess speech discrimination, you will be instructed to repeat words you hear. You will be asked to respond by raising your hand or pressing a button each time you hear a sound. You will wear headphones or earplugs connected to a device that sends sounds of different volumes and pitches to one ear at a time. A hearing test is performed in a sound proof room. Each test evaluates the potential for different kinds of hearing loss.ДЇigure 3. Before or after the general audiometry test, tuning forks are also used to conduct the Rinne and Weber tests. The audiologist will record each tone at the lowest possible volume that you were able to hear it. At some facilities, you may be asked to push a button or make some other sign that you have recognized a sound. For example, if you hear a sound with your left ear, raise your left hand if you hear a sound with your right ear, raise your right hand. The audiologist will ask you to raise your hand when you hear a sound. The earphones are connected to a machine that will deliver the tones and different sounds of speech to your ears, one ear at a time. You will be asked to sit still and not talk. The audiometry tests are conducted in a quiet soundproof room (Fig. Try your best to remain still and quiet during the test so that an accurate recording can be made.

There is no special preparation for the test. Hearing loss is often described as follows:ДЄn audiologist performs a hearing test. Audiogram of a patient with an acoustic neuroma shows hearing loss in the left ear. On an audiogram chart, red O's indicate the right ear's results and blue X's the left ear's results (Fig. Pure tone audiometry charts the hearing level of different tone frequencies in both ears. Acoustic reflex testing evaluates the cranial nerves and brainstem. Word recognition scores can be helpful in predicting the usefulness of a hearing aid.ДЄ tympanometry test detects problems such as fluid/wax buildup, perforated eardrum, ossicle bone damage, or tumors in the middle ear. If your speech discrimination is poor, speech may sound garbled. Normal hearing range is 250-8,000 Hz at 25 dB or lower.ДЄ word recognition test (also called speech discrimination test) assesses a person's ability to understand speech from background noise.

Low bass tones range 50-60 Hz, high-pitched tones range 10,000 Hz or higher. The tone of sound is measured in frequencies (Hz). A whisper is about 20 dB, loud music ranges 80-120 dB, and a jet engine is about 180 dB. The loudness of sound is measured in decibels (dB). During the test, you will wear earphones and hear a range of sounds directed to one ear at a time. The movement of hair cells generates nerve signals that our brain then understands as sound.ДЄ pure tone audiometry test measures the softest, or least audible, sound that a person can hear. When the vibration hits the cochlea, it causes the liquid, and subsequently the hair cells, to move. The cochlea is a spiral tube filled with liquid and lined with hair cells that are microscopic in size. The stapes delivers vibrations to the cochlea in the inner ear. The ossicles consist of the malleus, incus, and stapes. Vibrations are passed along tiny bones (ossicles) in the middle ear. Vibrations are made when sound hits the eardrum. The outer ear collects sound waves from the environment and funnels them down the ear canal to the eardrum.
