Acoustical performance and operation of the Maxxon acoustical laboratory
The Journal of the Acoustical Society of America, 2021This third and final presentation will cover the acoustical performance of the Maxxon facility including: (1) background noise from exterior sources (e.g., truck traffic serving an adjacent business and train traffic from a nearby railroad) and HVAC systems serving the building, (2) sound isolation from nearby spaces including the adjacent work area ...

The propulsor is the most important noise source. Low rotational speed and low tip speed are generally considered advantageous from a hydro-acoustic point of view. Hydroacoustic noise generated directly by a propulsor can be categorized into: cavitation noise; narrowband, (or tonal), noise; and broadband noise.

Acoustical designing for performers
The Journal of the Acoustical Society of America, 1977The normal procedure in acoustical designs usually emphasizes audience acceptance. This approach often results in unfavorable acoustical conditions for performing artists, both instrumental and vocal. The imbalance occurs form neglect of the musicians’ need for mutual communication, and too great an emphasis on achieving ’’optimum’’ reverberation ...

Acoustic OFDM System and Performance Analysis
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008This paper presents a technology for short-range communications using sound wave, in which the modulated data signal can be transmitted in parallel with regular audio without significantly degrading the quality of the sound. The technology, which we call Acoustic OFDM, replaces the high frequency band of the audio signal with OFDM carriers, each of ...

Performance statistics of the HEAR acoustic processor
ICASSP '79. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005The HEAR acoustic processor combines standard frequency-domain and cycle-synchronous time-domain parameters. Output segments, usually 10 msec. in length, vary dynamically from .1 msec. to over 100 msec. to capture significant events in the underlying acoustic phone structure.
