To investigate the effects of aging on loudness perception, equal-loudness-level contours were derived from loudness estimates for pure tones with various combinations of frequency and sound pressure level. The listeners were young and older adults who had otologically normal hearing. Comparison of the contours between listener groups revealed a large difference at frequencies higher than 1,000 Hz, indicating that substantial effects of age and gender existed: older listeners were less sensitive to high-frequency tones than young listeners. In addition, older males were even less sensitive to those tones than older females. Recruitment of loudness was also observable for older listeners at high frequencies. These findings suggest that the use of frequency-weighting A, which is based on the hearing characteristics of young people, in noise evaluation is questionable when senior citizens are assumed to be the listeners. Another method that takes the effects of aging into account should be developed to estimate the loudness of sounds perceived by older listeners more accurately.

“…Still, loudness judgments can be affected by a large variety of additional factors. These include other physical sound characteristics such as the spectral content or stimulus duration (overview in Jesteadt and Leibold, 2011), the particular task or context (Marks and Florentine, 2011;Arieh and Marks, 2011) as well as personal factors like the individual hearing status (Smeds and Leijon, 2011). Although being an especially important topic in the context of hearing loss, interindividual variability in loudness perception may be quite large even in a rather homogenous group of normal hearing listeners (see, e.g.…”

“…Here, "primarily" is a key adjective, since loudness is also affected by other physical dimensions such as duration, frequency, and bandwidth (for review, Jesteadt and Leibold, 2011). Almost all the sounds in our acoustic environment, including speech, are broadband in nature.…”

“…Differences in the growth of loudness as a function of frequency are often estimated from equal loudness contours (e.g., Jesteadt and Leibold, 2011;Scharf, 1978). Although Glasberg and Moore (2006) showed that their loudness model can predict the standard equal-loudness contours reasonably well, a direct comparison of their predicted contours and those in the current ISO (2003) standard [Jesteadt and Leibold (2011), Fig.…”

The loudness of broadband sound is often modeled as a linear sum of specific loudness across frequency bands. In contrast, recent studies using molecular psychophysical methods suggest that low and high frequency components contribute more to the overall loudness than mid frequencies. In a series of experiments, the contribution of individual components to the overall loudness of a tone complex was assessed using the molecular psychophysical method as well as a loudness matching task. The stimuli were two spectrally overlapping ten-tone complexes with two equivalent rectangular bandwidth spacing between the tones, making it possible to separate effects of relative and absolute frequency. The lowest frequency components of the "low-frequency" and the "high-frequency" complexes were 208 and 808 Hz, respectively. Perceptual-weights data showed emphasis on lowest and highest frequencies of both the complexes, suggesting spectraledge related effects. Loudness matching data in the same listeners confirmed the greater contribution of low and high frequency components to the overall loudness of the ten-tone complexes. Masked detection thresholds of the individual components within the tone complex were not correlated with perceptual weights. The results show that perceptual weights provide reliable behavioral correlates of relative contributions of the individual frequency components to overall loudness of broadband sounds.
