Assume supra-aural headphones.  Right Air Conduction: [RAC] Left Air Conduction: [LAC] Right Bone Conduction: [RBC] Left Bone Conduction: Already Masked

In the space provided, describe the type, configuration, degree, and symmetry of this hearing loss. Then, comment on the results you’d expect to see for Word Recognition Scores (WRS) in both ears.   

What type of tympanogram is this? [Type] What is the approximate ear canal volume? Assume a 226 Hz probe tone. [ECV]

TEOAEs (transient-evoked otoacoustic emissions) use click stimuli.

The TM (tympanic membrane) vibrates most efficiently when middle ear pressure is equal to ambient pressure.

What is the type of hearing loss in the left ear? [LEtype] What is the type of hearing loss in the right ear? [REtype] What best describes the hearing loss severity in the left ear? [LE] What best describes the hearing loss severity and configuration in the right ear? [RE] What is the symmetry? [sym]   What is the pure-tone average of the right ear? [PTA]   Based on the PTA, what is the severity of hearing loss in the right ear? [SPTA]   What acoustic reflexes would you expect for a 500 Hz stimulus? Left Ipsi: [500LI] Left Contra: [500LC] Right Ipsi: [500RI] Right Contra: [500RC]   What would you expect for a threshold to a click stimulus on an ABR (auditory brainstem response) in the right ear? [ABRR] What would you expect for a threshold to a click stimulus on an ABR (auditory brainstem response)in the left ear? [ABRL]   What level (dB HL) do you expect to see an SRT (speech recognition threshold) in the right ear? [SRT]

The procedure used when masking is called the ________________ method.

Otoacoustic emissions are generated by the inner hair cells.

Most etiologies of prenatal hearing loss are known. 

Name a disorder or condition that could result in the audiogram below.
