How do you read speech audiometry results?

How do you read speech audiometry results?

The numbers on the top ranking from 125 to 8000, are indicators for sounds frequencies. The higher that number, the higher is the pitch of the sound. On the left side, you can see the units for loudness, which is measured in decibels. Just as an example: A face-to-face conversation is about 65 decibels.

Is 4000 Hz high or low?

So if a child is having problems hearing fricatives, we need to check how they hear at 2000 Hz. High Frequencies: 4000 Hz provides more information on consonant production, third formant for vowels, noise bursts for plosives and affricates, turbulent noise of voiced and unvoiced fricatives.

What does otosclerosis look like on an audiogram?

On an audiogram, patients with otosclerosis commonly have conductive hearing loss with a drop in the bone-conduction threshold at 2,000 Hz, called a Carhart notch. This finding, in addition to an absent acoustic reflex, is generally thought to be diagnostic of otosclerosis.

What is a good WRS score?

Normal hearing and hearing impaired subjects. The number of correct words is scored out of the number of presented words to give the WRS. A score of 85-100% correct is considered normal when pure tone thresholds are normal (A), but it is common for WRS to decrease with increasing sensorineural hearing loss.

Can humans hear 4000 Hz?

In this case, this person cannot hear high-pitched sounds (4,000-8,000 Hz range) unless they are fairly loud. This will make hearing speech difficult. High-frequency hearing loss is a fairly common hearing loss pattern for people with age-related hearing loss.

How does an audiometry hearing test work?

The test uses a type of technology called an audiometer that can be connected to headphones, a speaker, or bone-conduction devices. The audiometer emits sounds that measure sound intensity and frequency. You can get an audiometry hearing test in a quiet space at a doctor’s office.

How is pure-tone audiometry used to evaluate hearing loss?

When hearing loss is suspected, pure-tone audiometry may be used to evaluate hearing deficits by spot-checking certain frequencies, or to evaluate deficits more completely.15 Pure-tone audiometry is performed with the use of an audiometer.

How do anatomic anomalies affect audiometry?

Audiometry results may be affected in patients with anatomic anomalies, such as narrow or collapsing ear canals (stenosis of the ear canal), complete canal occlusion, or absence of an ear canal (atresia). Impacted cerumen can cause a conductive hearing loss ( Figure 1) that typically resolves following cerumen removal.

How is audiometry used in family medicine?

Audiometry in the family medicine clinic setting is a relatively simple procedure that can be interpreted by a trained health care professional. Pure-tone testing presents tones across the speech spectrum (500 to 4,000 Hz) to determine if the patient’s hearing levels fall within normal limits.
