Chapter 10: Understanding and Interpreting the Audiogram

The letters of the alphabet found between 250 Hz and 750 Hz and from 30 dB HL and 65 dB are which type of sounds when spoken?

The letters in the alphabet found between 1500 and 6000 Hz and between 20 and 50 dB are which types of sounds when spoken?

The audiometric battery allows you to determine the extent of the loss of hearing. But, it does not allow you to determine the extent of the loss of understanding.

The patient who has reduced hearing usually equates hearing with understanding.

Normal hearing for a child ranges from _____ to _____ dB.

Normal hearing for an adult ranges from _____ to _____ dB.

A mild loss of hearing for an adult ranges from _____ to _____ dB.

A moderate loss of hearing for an adult ranges from _____ to _____ dB.

A moderately severe loss of hearing for an adult ranges from _____ to _____ dB.

A severe loss of hearing for an adult ranges from _____ to _____ dB.

A profound loss of hearing for an adult ranges from _____ to _____ dB.

Dotted vertical lines on the audiogram denote:

Frequencies are measured in:

Threshold levels are measured in:

Of the remaining five percent, the following conditions are included:

A mixed HL combines _____ with sensorineural HL.

Sensorineural HL is mainly due to the following:

Ossicular chain ossification leads to:

If bone conduction scores are elevated from AC scores but remain below 30 dB, the category of hearing loss is:

95% of the population of persons with hearing loss [PWHL] have a condition called:

If bone conduction scores are below AC scores by 40 dB or more, the type of hearing loss you are encountering is:

A positive response in the profound level of three frequencies in the lower octaves with NR [no response] in the higher frequencies is an example of:

Noise induced HL is usuall identified by a notch. This notch is a low threshold at _____ Hz.

A flat loss has generall less than 6 decibels per octave decline from lower octaves to higher octaves.

A sloping loss is indicative of what condition?

A precipitous HL has a slope that can be _____ dB/Octave or greater.

A mild reverse slope hearing loss is an indication of a genetic disorder or Meniere’s Disease.

Meniere’s disease patients generally will have the following loss.

When an audiogram demonstrates excellent hearing below 250 Hz and above 8000 Hz, but declines to low thresholds between 1000 and 2000 Hz, this is a _____ type of audiogram.

Using the Speech Banana allows you to:

The SRT [Speech Reception Threshold] is a dB level where the patient correctly hears/repeats Spondees at lease 90% of the time in the test.

The SRT level and the PTA level must be within about _____ dB to be deemed reliable.

A hearing screen can mislead a person with:

The area between the LDL [or UCL] and the SRT is _____.

The most comfortable listening level is determined by which instrument?

Speech Discrimination Scores [SDS] are tests given to measure whether simple acoustical signals are capable of being understood at a short distance.

If a noise in a room is twice as loud as the voice/signal, the ratio of signal-to-noise is:

Another test used to determine how well a patient can hear and understand in noisy acoustical environments is the _____ test.

You must re-administer the AC and BC tests if:

A serial audiogram test is performed _____ over _____ and are most likely used to track SSNHL.

Without an accurate audiometric battery, you cannot:

Medical intervention referrals are considered in the following battery results.

Your fitting potential in the population of persons with hearing loss will primarily consist of individuals with: (check all that apply)

Please list the four levels of speech discrimination percentages in reference to excellent, good to average, fair, and poor in order
