“…With the present technique we can minimize testing time without any appreciable loss of accuracy [John et al, 2001;Perez-Abalo et al, 2001]. Also, different statistical methods can be used to eliminate the bias introduced by human expertise in the interpretation of the results [Picton et al, 1987;Stapells et al, 1988;Dobie and Wilson, 1989;Valdes et al, 1997]. Moreover stimulus and recording parameters can be further optimized to make the technique more efficient [John et al, 1998;.…”

“…The length of such vector is the amplitude of the response while its rotation or angle (from the origin of the plane) would be the phase. To obtain these parameters (amplitude and phase) classical trigonometric functions were used as specified in Valdes et al [1997]. Even though both parameters were measured in the well babies MSSR, only the amplitude data will be reported here.…”

“…With the multiple-frequency SSR (MSSR) technique several frequencyspecific thresholds can be evaluated simultaneously, minimizing testing time and with no appreciable loss of accuracy John et al, 1998;PerezAbalo et al, 2001;Herdman and Stapells, 2001]. Also statistical indicators can be used to detect the signals automatically [Picton et al, 1987;Stapells et al, 1988;Savio, 1995;Valdes et al, 1997].…”

The Low and High Frequency Auditory Steady State Responses Mature at Different Rates

et al. 2001

The age-related changes in the fast rate (70–110 Hz) auditory steady state response elicited by multiple-frequency tones (MSSR) that were amplitude-modulated (AM) are reported here. The MSSR was recorded in a sample of 64 well babies distributed into three age groups: 0–29 days (n = 25); 1–6 months (n = 26); 7–12 months (n = 13). Four simultaneously presented AM tones (0.5, 1, 2 and 4 kHz) were delivered monaurally through TDH 49 earphones, at different intensities (between 90 and 30 dB SPL). Clear developmental changes were found between birth and 12 months of age in response threshold, amplitude and detectability. Statistical analysis revealed that these changes occurred at different rates for low- and high- frequency responses. Nonetheless adult-like hearing thresholds were estimated reasonably well in most newborns and well babies, for all frequencies tested. Therefore the MSSR technique could be useful for objective frequency-specific audiometry beginning at birth.

Bins were approximately 3 Hz in width, so the background noise was estimated for a range of about 48 Hz surrounding the modulation rate of the stimulus.…”

Evolutionary adaptations for the temporal processing of natural sounds by the anuran peripheral auditory system

Sensory systems function most efficiently when processing natural stimuli, such as vocalizations, and it is thought that this reflects evolutionary adaptation. Among the best-described examples of evolutionary adaptation in the auditory system are the frequent matches between spectral tuning in both the peripheral and central auditory systems of anurans (frogs and toads) and the frequency spectra of conspecific calls. Tuning to the temporal properties of conspecific calls is less well established, and in anurans has so far been documented only in the central auditory system. Using auditoryevoked potentials, we asked whether there are species-specific or sex-specific adaptations of the auditory systems of gray treefrogs (Hyla chrysoscelis) and green treefrogs (H. cinerea) to the temporal modulations present in conspecific calls. Modulation rate transfer functions (MRTFs) constructed from auditory steady-state responses revealed that each species was more sensitive than the other to the modulation rates typical of conspecific advertisement calls. In addition, auditory brainstem responses (ABRs) to paired clicks indicated relatively better temporal resolution in green treefrogs, which could represent an adaptation to the faster modulation rates present in the calls of this species. MRTFs and recovery of ABRs to paired clicks were generally similar between the sexes, and we found no evidence that males were more sensitive than females to the temporal modulation patterns characteristic of the aggressive calls used in male-male competition. Together, our results suggest that efficient processing of the temporal properties of behaviorally relevant sounds begins at potentially very early stages of the anuran auditory system that include the periphery.

In adults, the multiple-frequency 80-Hz ASSR technique can be used to determine the degree and configuration of hearing loss. Although air-conduction ASSR thresholds accurately predicted behavioral thresholds in CHL, future research with bone-conduction ASSRs is necessary to establish the type of hearing loss. Furthermore, the applicability of these findings still needs to be confirmed for infants.
