The building’s aging infrastructure needed a comprehensive modernization to meet accessibility requirements, the escalating requirements of contemporary performance, and to present a new face to the public as the premier cultural institution in the state capital. The existing theater’s acoustics represented a challenge to effectively accommodate the wide range of performance types including Broadway roadshows, the Sacramento Choral Society, and the Sacramento Philharmonic and Opera. Major renovations work included a complete exterior renovation; new mechanical, plumbing, electrical, and theatrical systems; and substantial updates to the interior finishes throughout the building. Providing an accessible venue to all patrons and performers was the primary goal of the project. Significant modifications to the external and internal circulation included removal of the entire audience chamber floor and new seating and aisle ways throughout. An electro-acoustic enhancement system was designed to provide an acoustically tunable audience chamber and electronic shell on stage to meet all the needs of the resident companies. Design and implementation of the electro-acoustic enhancement system will be discussed, including challenges of performer buy-in and audio orchestra shell integration.","PeriodicalId":256727,"journal":{"name":"The Journal of the Acoustical Society of America","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139326887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While hearing devices help to redress this challenge, there is often a mismatch between performance measures obtained in clinical and laboratory settings and observed real-world behaviour. This discrepancy is likely due to an array of parameters, with the most notable being unrealistic speech stimuli (e.g., contrived sentence materials), artificial background noise, and tasks that do not reflect real-world communication behaviour or scenarios (e.g., sentence recall). To bridge this gap, we used sensor-fusion to understand communication difficulties in familiar communication partners engaged in natural, unrestricted conversations while listening to different levels of realistic background noise. We tallied communication breakdowns as a robust, overt metric of communication difficulty and fused data from an array of sensors including microphones, eye and motion trackers, and wearables that detect autonomic nervous system activity to objectively index communication difficulty. Our approach aims to find biomarkers that may predict the communication difficulties faced by individuals with hearing loss in the real-world. Ultimately, this research will contribute to enhancing the effectiveness of hearing devices, leading to improved social connection and quality of life for people with hearing loss.","PeriodicalId":256727,"journal":{"name":"The Journal of the Acoustical Society of America","volume":"319 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139326911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We measured the environmental noise in Laguna de Términos, Campeche, México from 2004 to 2008 in stations distributed homogeneously in this lagoon during 17 sampling periods using a digital audio tape recorder sampling at 48 kHz with 16 bits for 1 min at each station. We also measured the environmental noise off Alvarado, Veracruz, México in June 2023 using a digital audio tape recorder sampling at 96 kHz with 24 bits for 50 min at four stations. The environmental noise in the recordings was measured with a semi-automatic MATLAB routine designed for this purpose. We will present preliminary results on the environmental noise in these two coastal locations using snapping shrimp sounds as a measure to depict differences in time and space within and between locations. Changes in submarine environmental noise are helping us in understanding the effects of natural phenomena and antropogenic sounds in the distribution and abundance of marine wildlife, such as snapping shrimps and bottlenose dolphins.

Psychophysical experiments are necessary to elucidate the processes which convey the spatial impression of sound sources. To this end, we propose a way to generate virtual stimuli for research on the spatial impression of musical instruments, specifically pianos. Our proposal, based on acoustical holography, takes a series of measurements over a dense grid and designs a virtual vibrating plate with the same directivity as the piano, as observed from the measuring grid. The number of active modes in the left-right and front-back directions of this virtual source can be controlled to reduce the radiation pattern complexity and generate a wide range of virtual stimuli. The resulting sound fields are rendered using binaural Ambisonics, using the position of the piano player as the spherical harmonic expansion center. The proposal was used in actual psychophysical experiments looking to shed light into the spatial impression of digital and acoustic pianos. The results show that the proposal does generate spatial sound signals which are consistently associated with different degrees of richness in the spatial impression.","PeriodicalId":256727,"journal":{"name":"The Journal of the Acoustical Society of America","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139327007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, RAP-based deep-sea acoustic communication may face channel model mismatch issues. In order to analyze the dynamic characteristics of spatial-temporalvariability channels, deep-sea mobile underwater acoustic channel measurement experiments were conducted. This work proposes a deep learning method based on multi-dimensional properties to classify deep-sea channels. Specifically, the sound ray convergence zone leads to a complex multipath structure and severe delay spread in the RAP channel. The fuzzy c-means (FCM) algorithm is used for multipath clustering to extract accurate channel features, and then the Markov chain (MC) is introduced to track the evolution characteristics of multipath clusters. Finally, the coupling features of channel time-variant impulse response (TVIR) and multi-dimensionalstatistical properties are used as the input of convolutional neural networks (CNNs) to obtain the quantitative evaluation index as the channel classification to build a channel feature dataset for underwater mobile platforms. This dataset can effectively assist in identifying deep-sea mobile channels and promote the development of adaptive underwater acoustic communication systems on mobile platforms.","PeriodicalId":256727,"journal":{"name":"The Journal of the Acoustical Society of America","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139327008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, it is understood that speaker dialects significantly influence formant frequencies. However, the specific interaction between dysarthria and speaker dialect remains a relatively unexplored area in research. This knowledge gap may hinder the generalizability of dysarthria findings from one regional dialect to speakers of other dialects. As an initial step in this research line, the current study investigates the interaction between regional dialects and dysarthria in Parkinson’s disease (PD) on vowel production. To do this, our study analyzes acoustic and kinematic data from speakers with and without dysarthria, representing Midwestern and Southern United States dialects. We examine both single-word repetitions and passage-reading contexts, recognizing that there may be a significant task effect. The study includes 50 speakers, with 24 speakers (10 PD, 14 control) from the Southern Dialect (collected in Louisiana and Florida) and 26 speakers (13 PD, 13 control) from the Upper Midwest dialect (collected in Wisconsin). The findings will shed light on the interaction between regional dialects and dysarthria, offering valuable insights for speech rehabilitation and understanding speech variations across different populations.","PeriodicalId":256727,"journal":{"name":"The Journal of the Acoustical Society of America","volume":"330 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139327245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
