“…We are, however, not aware of a specific study that measured the modulation frequency at which the percept of fluctuation strength transitions into a percept of roughness. At least for pure tones of very low frequency, it has been reported informally that below about 10 Hz, sound cycles can be perceived as 'distinct pressure pulses' and even be counted (Jurado et al, 2020;Møller & Pedersen, 2004). This agrees with early results by Lechelt (1975), who showed that a series of short sound clicks presented at low repetition rates (their highest rate was 8 Hz) can be counted with accuracy.…”

“…On the one hand, it has been reported that for repetition rates below about 20 Hz, the sensation of pitch ceases (Guttman & Pruzansky, 1962;Warren & Bashford, 1981). On the other hand, reports have also described infrasound as having a 'discontinuous' perceptual quality (Jurado et al, 2020;Møller & Pedersen, 2004). This notion of perceptual segregation at low repetition rates is shared among different sensory modalities.…”

What sound quality has led to exclude infrasound from sound in the conventional hearing range? We examined whether temporal segregation of pressure pulses is a distinctive property and evaluated this perceptual limit via an adaptive psychophysical procedure for pure tones and carriers of different envelopes. Further, to examine across-domain similarity and individual covariation of this limit, here called the critical segregation rate (CSR), it was also measured for various periodic visual and vibrotactile stimuli. Results showed that sequential auditory or vibrotactile stimuli separated by at least ~80‒90 ms (~11‒12-Hz repetition rates), will be perceived as perceptually segregated from one another. While this limit did not statistically differ between these two modalities, it was significantly lower than the ~150 ms necessary to perceptually segregate successive visual stimuli. For the three sensory modalities, stimulus periodicity was the main factor determining the CSR, which apparently reflects neural recovery times of the different sensory systems. Among all experimental conditions, significant within- and across-modality individual CSR correlations were observed, despite the visual CSR (mean: 6.8 Hz) being significantly lower than that of both other modalities. The auditory CSR was found to be significantly lower than the frequency above which sinusoids start to elicit a tonal quality (19 Hz; recently published for the same subjects). Returning to our initial question, the latter suggests that the cessation of tonal quality — not the segregation of pressure fluctuations — is the perceptual quality that has led to exclude infrasound (sound with frequencies < 20 Hz) from the conventional hearing range.

“…The latter three studies reveal an activation of the primary auditory cortex, which supports the hypothesis that infrasound is processed by the auditory system. In agreement with this hypothesis, several psychoacoustic studies have shown that pure tones with frequencies down to at least 2 Hz can be detected by the auditory system (e.g., [15][16][17][18][19][20]; for a review, see Møller and Pedersen [21]). The sound pressure levels at threshold-in the following simply referred to as thresholds-are higher than those for frequencies in the classical audio-frequency range (between 20 Hz and 20 kHz) and increase with decreasing frequency.…”

“…An exponent of 3 would result in a slope s, expressed as threshold change per doubling of duration, of -2 dB. Table 3 shows the slopes, s, and the offsets, L O , of straight lines fitted to the grand mean thresholds of the MB stimuli (see top row of Fig 3) as well as the exponents, â, derived from the slopes by the equation â ¼ À 20 s lg 2 ð Þ. Note that the thresholds for the shortest duration in the 16Hz_3C condition, i.e., for MB1, deviate from a straight line.…”

Infrasounds are signals with frequencies below the classical audio-frequency range, i.e., below 20 Hz. Several previous studies have shown that infrasound is audible as well, provided that the sound level is high enough. Hence, the sound pressure levels at threshold are much higher than those in the classical audio-frequency range. The present study investigates how the duration and the shape of the temporal envelope affect thresholds of infrasound stimuli in quiet. Two envelope types were considered: one where the duration of the steady state was varied (plateau bursts) and one where the number of consecutive onset–offset bursts was varied (multiple bursts). Stimuli were presented monaurally to human listeners by means of a low-distortion sound reproduction system. For both envelope types, thresholds decrease with increasing duration, a phenomenon often referred to as temporal integration. At the same duration, thresholds for plateau-burst stimuli are typically lower than those for multiple-burst stimuli. The data are well described by a slightly modified version of a model that was previously developed to account for temporal integration in the classical audio-frequency range. The results suggest similar mechanisms underlying the detection of stimuli with frequencies in the infrasound and in the classical audio-frequency range. Since the model accounts for the effect of duration and, more generally, the shape of the envelope, it can be used to enhance the comparability of existing and future datasets of thresholds for infrasounds with different temporal stimulus parameters.

“…To this end, Bayesian inference in an updated maximum likelihood (UML) procedure was used (Shen & Richards, 2012). This adaptive procedure has proved reliable in various psychophysical tests; for instance, in the field of psychoacoustics (Carcagno & Plack, 2021;Fischer et al, 2021a,b;Lee & Müllensiefen, 2020;Jurado et al, 2020). The method can estimate the reliability of the results by calculating a credible interval, the Bayesian equivalent to the confidence interval in frequentist statistics (Comotto, 2022).…”

Matrix sentence tests in noise can be challenging to the listener and time-consuming. A trade-off should be found between testing time, listener’s comfort and the precision of the results. Here, a novel test procedure based on an updated maximum likelihood method was developed and implemented in a German matrix sentence test. It determines the parameters of the psychometric function (threshold, slope, and lapse-rate) without constantly challenging the listener at the intelligibility threshold. A so-called “credible interval” was used as a mid-run estimate of reliability and can be used as a termination criterion for the test. The procedure was evaluated and compared to a STAIRCASE procedure in a study with 20 cochlear implant patients and 20 normal hearing participants. The proposed procedure offers comparable accuracy and reliability to the reference method, but with a lower listening effort, as rated by the listeners ([Formula: see text] points on a 10-point scale). Test duration can be reduced by 1.3 min on average when a credible interval of 2 dB is used as the termination criterion instead of testing 30 sentences. Particularly, normal hearing listeners and well performing, cochlear implant users can benefit from shorter test duration. Although the novel procedure was developed for a German test, it can easily be applied to tests in any other language.
