Subjective Evaluation of an Emerging Theory of Low-frequency Sound Source Localization in Closed Acoustic Spaces
The primary aim of sound reproduction is to accurately recreate naturally-occurring sound fields. Due to reproduction system limitations, however, compromises must be made to allow for practical sound reproduction. In regards to low-frequency sound reproduction, a common assumption is that humans cannot detect direction at low-frequencies or that in the presence of a broadband signal, low-frequ...
متن کاملMeasurement of complex acoustic intensity in an acoustic waveguide.
Acoustic intensity is normally treated as a real quantity, but in recent years, many articles have appeared in which intensity is treated as a complex quantity where the real (active) part is related to local mean energy flow and the imaginary (reactive) part to local oscillatory transport of energy. This offers the potential to recover additional information about a sound field and then to rel...
متن کاملField Test of a Low-frequency Sparker Source for Acoustic Waveform Logging
Low-frequency acoustic-energy sources for waveform logging have important applications in: 1) Verifying theoretical calculations; 2) generating tube waves in large-diameter boreholes; and 3) providing larger sample volumes in cases where borehole effects are important. A new low-frequency source was fabricated by modifying an existing acoustic-waveform logging system to discharge multiple capac...
متن کاملSound source localization by hearing preservation patients with and without symmetrical low-frequency acoustic hearing.
The aim of this article was to study sound source localization by cochlear implant (CI) listeners with low-frequency (LF) acoustic hearing in both the operated ear and in the contralateral ear. Eight CI listeners had symmetrical LF acoustic hearing and 4 had asymmetrical LF acoustic hearing. The effects of two variables were assessed: (i) the symmetry of the LF thresholds in the two ears and (i...
