17 Questions
What type of speech sounds are particularly dependent on extended high frequency (EHF) energy for recognition?
Consonants
What does 'EHF hearing loss' refer to?
Hearing loss in the extremely high frequencies
Why are older adults with EHF hearing loss worse than younger adults at determining sound elevation?
Because of basal cochlear damage
Which type of energy dominates in the standard clinical frequency range of speech?
Low-frequency energy
How does EHF hearing loss impact cochlear functioning in standard frequencies?
It has no effect on cochlear functioning
How is extended high frequency (EHF) hearing loss described in terms of preventability?
Partially preventable
What is a potential connection between 'normal audiogram' and absent OAEs?
EHF hearing loss
What is suggested as an early predictor of future hearing impairment in the standard frequencies?
EHF hearing loss
What was significantly lower for EHF-impaired adults in the 2-5 kHz region?
Distortion product otoacoustic emissions (DPOAEs)
What should be done to minimize the effects of otitis media on children's hearing according to the text?
Monitor hearing frequently
Which age group experiences the highest percentage of EHF hearing loss?
4 to 5-year-olds
What is one of the causes of EHF hearing loss mentioned in the text?
Excessive use of personal listening devices
How is noise-induced hearing loss (NIHL) typically represented in an audiogram according to the text?
A dip in the high-frequency range
What type of diseases are mentioned as potential contributors to EHF hearing loss?
Autoimmune rheumatic diseases
How does systemic disease affect hearing loss, as per the text?
It makes hearing loss detection difficult
What is the significance of the EHF loss preceding the 'notch' at lower frequencies?
It suggests a more serious type of hearing loss
Why might EHF audiometry be preferred over conventional PTA for certain systemic diseases?
Because it is more likely to detect the hearing loss
Test your knowledge on EHF (extended high frequency) hearing loss and hearing impairment, which can co-occur with standard frequency hearing issues. Learn about the elevated thresholds in the EHF range and its prevalence in the general population.
