“…Kiang et al (1963) first identified the PAMR, which was referred to in early papers as the 'sonomotor response' (e.g. Davis & Lowell, 1965) or the 'crossed acoustic response' (Douek et al, 1973;Humphries et al, 1976). The latter name arises from the fact that the PAMR can be evoked bilaterally from monaural sound stimuli such as clicks or tonebursts (Yoshie & Okudaira, 1969).…”

Post-auricular muscle responses (PAMRs) were recorded in sixteen adults with normal hearing and twenty adults with sensorineural hearing loss. Click stimuli were presented at 20 to 80 dB nHL via insert earphones. Only one ear was tested in hearing-impaired subjects, but normal-hearing subjects were tested monaurally and binaurally. PAMR amplitudes declined and latencies increased with decreasing click intensity. Both binaural stimulation and eye turn enhanced the PAMR. In hearing-impaired subjects, PAMR thresholds were correlated with audiometric thresholds for the eyes-turned condition. All normal-hearing subjects had PAMR when recording conditions were optimized and half had responses for the least optimal condition (20 dB nHL, monaural, eyes front). With eyes turned and monaural clicks at 35 dB nHL, the level widely used for infant hearing screening, most normal-hearing adults had a PAMR. Thus the PAMR is a robust response that may be a useful adjunct to ABR for objective hearing assessment.

“…The human AER consists of an early component (0-12 ms) which includes the brainstem auditory evoked response (BAER), an auditory middle-latency response (12-50 ms), dominated in many cases by the myogenic postauricular muscle response (PAMR) [Bochenek and Bochenek, 1976;Davis et al, 1965;De Grandis and Santoni, 1980;Douek et al, 1973Douek et al, , 1974Douek et al, , 1975Dus and Wilson, 1975;Gibson, 1975], and a series of longer-latency responses occurring 50-1000 ms after the acoustic stimulus. Of these responses, the BAER is used most often in screening infants for hearing impairment, largely due to its reliability, even during sleep.…”

Auditory Evoked Response Test Strategies to Reduce Cost and Increase Efficiency: The Postauricular Muscle Response Revisited

We describe a number of techniques in auditory evoked response (AER) testing for hearing loss which should decrease its cost and increase its efficiency, making its use in infant hearing screening more viable. We demonstrate the use of bit-stream averaging of the electrical signals from the head as a cheap alternative to analogue averaging and show that the average waveforms obtained are similar with both techniques. We demonstrate how the postauricular muscle response (PAMR) can be potentiated by lateral rotation of the eyes and argue that uncontrolled eye movements in previous studies have led to an unfounded belief that the PAMR is not stable. When eye rotation is used to potentiate the PAMR, the response becomes very stable and so large in most subjects that it is clearly visible in the raw traces. We also demonstrate that when the PAMR is potentiated by eye rotation, stable PAMR waveforms can be reliably obtained with tone bursts with frequencies up to and above 8 kHz and with sound levels within 30 dB of the subjective detection threshold. As a result the PAMR can be used to rapidly determine an objective audiogram in most subjects within minutes. Finally, we demonstrate a correlation technique for detecting the PAMR without waveform averaging and the need for an expensive computer. We are sure that a combination of these techniques can be used to increase the efficiency of AER screening for infant deafness and lower its cost dramatically.

“…The crossed acoustic response (CAR) (Yoshie et al, 1969;Thornton, 1975;Humphries et al, 1976a, b) was the myogenic response from the postauricular muscles to monaural clicks as described by Douek et al (1973). This is a bilateral response which crosses the brainstem and involves a pathway between one ear and the postauricular muscles of both sides.…”
