Parncutt develops a model of Western tonal music on the basis of psychoacoustics and psychomusicology and applies the model to the identification of the specific effects of musical conditioning and to the analysis of musical compositions. Included are interesting studies of analytic vs. synthetic, etc. listening preferences for both musicians and nonmusicians (categorizing listeners according to their listening styles).

Patterson, R. D. "Guidelines for Auditory Warning Systems on Civil Aircraft." Paper No. 82017, Civil Aviation Authority, London, 1982.

One of the first and best papers to discuss the proper structure of auditory warning signals based on psychoacoustical principles.

Peacock, K. "Synesthetic Perception: Alexander Scriabin's Color Hearing." Music Percep. 2(4) (1985): 483--506.

A curious phenomena which has surfaced repeatedly since the late Baroque era has come to be known as synaesthesia. It was used by the Romanticists of the nineteenth century as an effective means to enrich their accounts of sensuous impressions. Other names for the phenomena include chromesthesia, photothesia, synopsia, color hearing, and color audition. People who have this characteristic, experience a crossover between one or more sensory modes. Thus, they might be blessed with the ability to hear colors or odors, or see sounds. People who habitually perceive stimuli in this manner are often surprised when told that not everyone shares this faculty. Color hearing, though only one form of synaesthesia, is probably the commonest.

Perrott, D. R., K. Saberi, K. Brown, and T. Z. Strybel. "Auditory Psychomotor Coordination and Visual Search Performance." Percep. & Psycho. 48 (1990): 214--226.

The authors postulate that the primary function of the auditory spatial system is to direct the eyes. They studied the visual search time for targets presented with and without associated spatial audio cues and found that presenting a 10-Hz click train from the same location as the visual target substantially reduced the time for visual search.

Visual search performance in displays with distracters was studied with and without spatially correlated audio cues. The value of audio in directing visual search was found to be particularly great when there were a large number (63) of distracter images. Potential in applications such as enhanced cockpit displays is noted.

A description of experiments on using sounds to guide navigation in graphical user interfaces.

Plomp, R., and W. J. M. Levelt. "Tonal Consonance and Critical Bandwidth." J. Acous. Soc. Am. 38 (1965): 548--560.

Musicians' rank harmonic intervals in terms of their consonance and dissonance differently than naive subjects. For nonmusicians, consonance and "pleasantness" are one and the same. This is not true for trained musicians who often consider dissonances more pleasant for reasons of harmony or aesthetics.

Plomp, R. "Acoustical Aspects of Cocktail Parties." Acustica 38 (1977): 186--191.

Plomp considers cocktail parties in terms of signal-to-noise ratio and speech intelligibility. He discovers the importance of room acoustics--the height of the hall and the sound absorption characteristics of the ceiling and walls.

Pollack, I., and L. Ficks. "Information of Elementary Multidimensional Auditory Displays." J. Acous. Soc. Am. 26 (1954): 155--158.

The authors consider two different mappings of multidimensional data onto the parameters of sound. Using these two display types, they measure the information transmitted to subjects as the sum of the number of bits in each correctly identified dimensional level. Their results indicate that multidimensional displays, in general, outperformed unidimensional displays measured elsewhere, and that subdivision of display dimensions into finer levels does not improve information transmission as much as increasing the number of display dimensions does.

Pohlmann, Ken C., ed. Advanced Digital Audio. ISBN 0-672-22768-1. SAMS, 1991.

An excellent book covering a variety of advanced topics in digital signal processing for audio. It covers several formats (optical disk technology, digital audio systems for video and film, data compression, signal processing for audio, and DSP architecture).

Pratt, C. C. "Music as the Language of Emotion." Lecture delivered in the Whittall Pavilion of the Library of Congress, December 21, 1950. Washington, DC: US Government Printing Office, 1952.

In a study involving 227 college students, the author finds a strong consensus as to the mood conveyed in four distinct pieces of music that cannot be accounted for by the status of music as a language of emotions.
