“…In addition, threshold for detection of a pure tone can be estimated. We have used the technique as described above to obtain detection thresholds for 3-, 6-, and 12-month-olds, at frequencies ranging from 250 to 4000 Hz, The first issue was whether OPP could give us thresholds for pure tones at least as good as the ones that we obtained from 6-month-olds using conditioned head-turns in a previous study (Olsho, 1985). We compared these with thresholds for 6-montholds obtained using OPP.…”

“…The average thresholds and standard errors obtained by Olsho (1985) at 500, 1000, and 4000 Hz are shown in Figure 1; six infants are included at each frequency. Also in Figure 1 are average thresholds and standard errors for thirty-seven 6-month-olds using OPP: 12 infants at 500 Hz, 13 at 1000 Hz, and 12 at 4000 Hz.…”

“…Frequency and intensity difference thresholds have been estimated (e.g., Olsho, 1984b;Sinnott & Aslin, 1985). The infant's ability to detect sounds in the presence of competing sounds has also been investigated (e.g., Bull, Schneider, & Trehub, 1981;Nozza & Wilson, 1984;Olsho, 1985). The literature on infant speech discrimination and categorization is substantial (see Aslin, Pisoni, & Jusczyk, 1983, for a review).…”

“…We chose to make our new procedure as similar as possible to our original conditioning procedure (e.g., Olsho, 1984bOlsho, , 1985Olsho,Schoon,Sakai,Turpin&Sper-duto, 1982a, 1982b) so that we could compare thresholds obtained using conditioned head-turn responses with those obtained using an observer-based procedure for infants at 6 months of age. Any differences between the two types of thresholds, then, could be accounted for by the response measure, rather than by differences in the number of signal intervals, signal presentation mode, or other procedural variables.…”

This article describes an observer-based technique for assessing auditory capacities of infants from 3 to 12 months of age. This technique, referred to as the Observer-based Psychoacoustic Procedure (OPP), combines features of the Forced-choice Preferential Looking technique developed by Teller (1979) and of Visual Reinforcement Audiometry (Moore ; Thompson, & Thompson, 1975). The rationale behind the procedure and the specific techniques used in its application are detailed here. Psychometric functions and thresholds for pure-tone detection and frequency discrimination obtained with OPP are also presented. The results for 6-month-olds are compared with results from previous studies employing a visually reinforced head-turn procedure. 627

A. Auditory filter shapes at low frequenciesWe recently established two important findings on frequency tuning in the human inner ear. First, tuning was sharper than previously thought, and sharpened considerably with increasing frequency from 1000 to 8000 Hz; second, human tuning was sharper by a factor of two than that found in other mammals that are often used as models of human hearing (Shera, Guinan & Oxenham, 2002; PNAS 99:3318-23). The technique used that in that study was suitable only for frequencies at and above 1000 Hz. Important speech information is carried at lower frequencies, particularly when the speech is mixed with interfering sources. We have therefore developed a behavioral technique that allows us to estimate human filter shapes at lower frequencies. We find that the divergence between our new measures and the earlier estimates of filter tuning are less at low than at high frequencies and we are now in the position to provide a complete estimate of low-level human cochlear filter tuning from 250 Hz to 8000 Hz.

Developmental changes in chickens' masked thresholds

Masked thresholds were estimated at four frequencies (.25, .5, 1, and 2 kHz) in three levels of broadband noise (approximately 0, 10, and 20 dB/Hz) in over 100 chickens at 0 and 4 days of age. An adaptive procedure was based on delays in ongoing peeps that occurred when chicks heard the tones over the background noise. Masked thresholds decreased an average of 1 dB per day immediately after birth. This increasing sensitivity is more likely due to nonsensory factors, similar to distraction masking reported in human neonates, than to improving frequency resolution. Masked thresholds in these neonates are otherwise affected by spectrum level and frequency in the same way as the responses of mature subjects: thresholds increase by nearly 1 dB for each dB of increase in the spectrum level of the masker, and by approximately 3 dB for each octave of frequency. Thus, although elevated by some nonsensory effect, masked thresholds in newborn chicks are similar to those in humans.
