• Physical synthesis of six-string guitar plucks using the Udwadia-Kalaba modal formulation August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page 575-587, August 2020. Extending the previous work done by the authors, this paper develops a time domain synthesis method for the classical guitar based on substructuring concepts and using the Udwadia-Kalaba modeling strategy. Adopting a modal description of the dynamics of the […]

• Investigation of a directional warning sound system for electric vehicles based on structural vibration August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page 588-598, August 2020. Warning sound systems for electric vehicles with advanced beamforming capabilities have been investigated in the past. Despite showing promising performance, such technologies have yet to be adopted by the industry, as implementation costs are generally too high and the […]

• Additional length model for the impedance end correction of microperforated panels August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page 566-574, August 2020. An additional length model is usually used to describe the reactive part of the impedance end correction of microperforated panels, which is extended to describe the resistive part. The cross-sectional impedance is computed along the axis of one perforation […]

• Lack of reproducibility of temporary hearing threshold shifts in a harbor porpoise after exposure to repeated airgun sounds August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page 556-565, August 2020. Noise-induced temporary hearing threshold shift (TTS) was studied in a harbor porpoise exposed to impulsive sounds of scaled-down airguns while both stationary and free-swimming for up to 90 min. In a previous study, ∼4 dB TTS was elicited in this porpoise, […]

• Latency-dependent filtering and compact representation of the complete auditory pathway response August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page 599-613, August 2020. Auditory evoked potentials (AEPs) include the auditory brainstem response (ABR), middle latency response (MLR), and cortical auditory evoked potentials (CAEPs), each one covering a specific latency range and frequency band. For this reason, ABR, MLR, and CAEP are usually […]

• Differential orthogonal frequency division multiplexing communication in water pipeline channels August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page EL130-EL134, August 2020. The problem of information transmission through water pipelines is addressed and a class of methods based on differentially encoded orthogonal frequency division multiplexing (OFDM) is proposed. Specifically, two methods are investigated; one based on conventional differential encoding with an […]

• Interaction of prosody and syntax-semantics in Mandarin wh-indeterminates August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page EL119-EL124, August 2020. This paper reports on two speech-production experiments focused on Putonghua and Taiwan Mandarin sentence-final particles and wh-phrases that have interrogative or indefinite readings in three contexts: yes/no questions, wh-questions, and statements. Sentence-final particles were found to influence focus-prosody through […]

• Teaching-learning-based optimization of a composite metastructure in the 0–10 kHz broadband sound absorption range August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page EL125-EL129, August 2020. This paper proposes a strategy to broaden the sound absorption region of porous materials by embedding ribs. The theoretical solution and the numerical simulations of the optimization model show that the composite metastructure exhibits ultra-wide high absorption characteristics and […]

• The Lombard effect in singing humpback whales: Source levels increase as ambient ocean noise levels increase August 4, 2020
  The Journal of the Acoustical Society of America, Volume 148, Issue 2, Page 542-555, August 2020. Many animals increase the intensity of their vocalizations in increased noise. This response is known as the Lombard effect. While some previous studies about cetaceans report a 1 dB increase in the source level (SL) for every dB increase in […]
