On a standard audiogram, presbycusis appears as an overall down-sloping line that represents impaired hearing at higher frequency sounds. Laboratory testing for diseases commonly associated with hearing loss, such as dyslipidemia, diabetes, and renal dysfunction, may be indicated but are not required for diagnosis.
Audiometric shape and presbycusis
https://pubmed.ncbi.nlm.nih.gov/19363723/
Gender and noise/solvent-exposure effects on the prevalence of the different audiogram shapes were determined statistically. In our population 'Flat' audiograms were most dominantly represented (37%) followed by 'High frequency Gently sloping' audiograms (35%) and 'High frequency Steeply sloping' audiograms (27%).

In this type slope of the audiogram occurs in the high frequencies therefore the speech discrimination is preserved. Neural presbycusis is result from nerve cells atrophy in the cochlea and central neural pathway. Atrophy occurs throughout the cochlea with no precipitous drop in high-frequency threshold in the audiogram.

The subjects were selected for this study because no cause of their hearing loss could be found other than presbycusis. They all had the typical moderately sloping pure tone audiogram configuration. The pure tone average hearing loss (PTA, average of 0.5, 1 and 2 kHz) ranged from 11 to 70 dBHL with a median of 40.

Sensory (hair cell) presbycusis in particular is characterized by a precipitous high tone loss, ie, the high-frequency steeply sloping pattern (13). Loss of peripheral neurites in the anterior basal cochlear segment is associated with a gradual down-sloping audiogram, ie, the high-frequency gently sloping pattern ( 13 ).

Presbycusis is the loss of high frequency sensivity with age. A pure tone audiogram will resemble fig.1. When prescribing hearing aids the audiogram will guide the degree of amplification required at various frequencies.

– Describe the audiogram by configuration from least amount of hearing loss to the most (ex: mild to severe) – Pure tone average is 500 Hz, 1000 Hz, and 2000 Hz added and divided by 3. Degree of hearing loss Degree of hearing loss: • 0‐15 dB WNL • 16‐25 dB Slight • 26‐40 dB Mild

Based on temporal bone analyses correlating the patterns of hearing loss with defect location, Schuknecht proposed three major forms of ARHL: (i) sensory presbycusis characterized by an abrupt pure-tone threshold elevation in the high frequencies and hair-cell loss at the basal end of the cochlea; (ii) strial presbycusis found in patients with a flat- or slightly …
