Available in PDF, EPUB and Kindle. Book excerpt: A loudspeaker-driven simulation booth with extended rise time capability (down to 0.22 ms) has been used for subjective loudness tests of sonic-boom and other types of impulsive sounds. The first series compared N-waves over a range of 0.22 to 10 ms rise time, 100 to 250 ms duration and from 0.5 to 4 psf (the latter for the longer rise times) (24 to 192 N/sq m) peak overpressure. The response tradeoff between rise time and overpressure, and duration and overpressure was measured. The second series tested certain 'flat top' sonic boom signatures, which according to current theory could be generated by special very long SST aircraft designed for minimized sonic-boom; these were compared for loudness with a reference N-wave (pN = 0.5 psf, 1 ms rise time, 150 ms duration). The third series compared filtered N-wave signatures, using a highpass digital filter with an unfiltered N-wave signature (1 psf, 1 ms rise time, 150 ms duration). In the last test series the tradeoff between overpressure and duration was found for idealized quarry blast signatures composed of sequences of 25 ms long pulses with 0.22 ms rise time. The range of durations extended from 25 to 400 ms. The results in each series were compared with theoretical predictions by the method of Johnson and Robinson. All but the long-duration quarry blast judgements were found to be in very good agreement in terms of relative loudness levels.

Download or read book Sound Reproduction written by Floyd E. Toole and published by Routledge. This book was released on 2017-07-28 with total page 956 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms, Third Edition explains the physical and perceptual processes that are involved in sound reproduction and demonstrates how to use the processes to create high-quality listening experiences in stereo and multichannel formats. Understanding the principles of sound production is necessary to achieve the goals of sound reproduction in spaces ranging from recording control rooms and home listening rooms to large cinemas. This revision brings new science-based perspectives on the performance of loudspeakers, room acoustics, measurements and equalization, all of which need to be appropriately used to ensure the accurate delivery of music and movie sound tracks from creators to listeners. The robust website (www.routledge.com/cw/toole) is the perfect companion to this necessary resource.
