Relating Approach-to-Target and Detection Tasks in Animal Psychoacoustics
Psychophysical experiments seek to measure the limits of perception. While straightforward in humans, in animals they are time consuming. Choosing an appropriate task and interpreting measurements can be challenging. We investigated the localization of high-frequency auditory signals in noise using an "approach-to-target" task in ferrets, how task performance should be interpreted in terms of p...
متن کاملHistory of Psychoacoustics
Psychoacoustics, or rather Psychological Acoustics, plays a significant role to date in many areas of application within acoustics. It therefore has a long and vast history to look back upon. Within its history, one central figure is definitely Hermann von Helmholtz. He paved the way for interdisciplinary acoustic r esearch in his genius book “Die Lehre von den Tonempfindungen”. At his laborato...
متن کاملPsychoacoustics and Sound Quality
In this chapter psycho-physical methods which are useful for both psycho-acoustics and sound-quality engineering will be discussed, namely, the methods of random access, the semantic differential, category scaling and magnitude estimation. Models of basic psycho-acoustic quantities like loudness, sharpness and roughness as well as composite metrics like psycho-acoustic annoyance will be introdu...
متن کاملReverberation Echo Density Psychoacoustics
A series of psychoacoustic experiments were carried out to explore the relationship between an objective measure of reverberation echo density, called the normalized echo density (NED), and subjective perception of the time-domain texture of reverberation. In one experiment, 25 subjects evaluated the dissimilarity of signals having static echo densities. The reported dissimilarities matched abs...
متن کاملCritical bands and critical ratios in animal psychoacoustics: an example using chinchilla data.
This paper suggests that critical ratios obtained in noise-masked tone studies are not good indicators of critical bandwidths obtained in both human and nonhuman animal subjects. A probe-tone detection study using chinchilla subjects suggests that they may be broadband processors in detection tasks as opposed to human subjects who use narrow-band, critical-band processing. If chinchilla and oth...
