I got the report from Buffalo Speech and Hearing in the mail today for Nolan. The results are a little worse than what the audiologist wrote down on Wednesday, but the effect is still the same (hearing aids). His hearing threshholds are:
Left ear:
500Hz 60dB
1000Hz 50dB
4000Hz 35dB
Right ear:
500Hz 55dB
1000Hz 50dB
4000Hz 30dB
The official report reads:
Tympanometry revealed normal Type A curves in both ears indicating normal middle ear function.
An Otoacoustic Emissions (OAE's) Study was performed in both ears. OAEs are frequently used to determine cochlear function, which allows us to infer about peripheral hearing acuity. LEFT EAR: Test results revealed reduced cochlear function from 500-8000Hz. RIGHT EAR: Test results revealed reduced cochlear function from 500-2000Hz with normal cochlear function from 3000-8000Hz.
Auditory Brainstem Response (ABR) was performed as a threshold search in both ears. Results are as follows:
Left Ear: Using air conducted clicks, best responses for Wave V were obtained at 35dB HL. Best responses to a 500Hz tone burst were obtained at 60dB HL. Best response to a 1000Hz tone burst were obtained at 50dB HL. These results are suggestive of a moderate sensorineural hearing loss sloping upward to normal.
Right Ear: Using air conducted clicks, best responses for Wave V were obtained at 30dB HL. Best responses to a 500Hz tone burst were obtained at 55dB HL. Best response to a 1000Hz tone burst were obtained at 50dB HL. These results are suggestive of a mild/moderate sensorineural hearing loss sloping upward to normal.
Summary: The ABR test results suggest that Nolan has a mild/moderate sensorineural hearing loss sloping upward to normal bilaterally. OAEs are fairly consistent with the ABR thresholds.
Recommendations:
1. Physician to review test results.
2. Repeat ABR to confirm degree and configuration of hearing loss.
3. Nolan was scheduled to see an ENT today.
4. Make contact with Early Intervention for services.
5. Hearing aid evaluation pending next results.

Get on those Early Intervention people and get them to see Nolan ASAP. Don't be nice about it. Let them know you mean business! :)
