Chapter 3, Problem B3CR

Describe how the anatomy of the cochlear auditory pathway enables normal auditory sensorineural physiology. BIU = = H 19: = = = 1 3 HT >

Why is masking of the non-test ear recommended and used in speech audiometric assessment using supra-aural headphones, especially when the client being tested has normal hearing sensitivity? (Hint: What is inter-aural attenuation, and how does this affect the testing paradigm?)

I need assistance with how to read Fletcher Munson graphs. Please help and show me the proper way to analyze these graphs. The previous experts I've asked on this platform were incorrect.

Why is masking only used sometimes when testing hearing?

A student is trying to calculate the QALY loss associated with a 75 year old mna suffering permanent hearing loss. She knows that the average life expectancy of men is 82 years old, and that from EQSD studies hearing loss leads to a quality of life that is 80% of the norm. She calculates the total loss as 0.8 x 7= 5.6 QALYS. Identify 3 errors that the student has made in their calculations and explain how these should be corrected. Thank you!

Name and discuss one factor that influence audiometric hearing threshold during pure-tone and/or speech audiometric assessment. How and why would this factor influence audiometric threshold?

Apparently, infants can imitate facial expression almost at birth, but have 20/200 to 20/400 vision at birth. Provide a rationale for understanding this apparent inconsistency.

More than 1.1 billion young adults are at risk for hearing loss according to World Health Organization (WHO, 2015). The primary reason is increasing use of personal audio devices with headphones or earphones. Hearing loss is of two main types: conduction deafness and perception deafness. Young adults are more likely to experience perception or nerve deafness. Which of the following parts of the ear is not involved in nerve deafness? Select one: a. Organ of Corti b. Semicircular canal C. Auditory nerve and basilar membrane d. Sensory neurons and hair cells
