Accuracy Analysis of the Multiparametric Acoustic Indices AVQI, ABI, and DSI for Speech-Language Pathologist Decision-Making.

Journal of Voice, 2023
PURPOSE To investigate the accuracy of the Acoustic Voice Quality Index (AVQI), the Acoustic Breathiness Index (ABI), and the Dysphonia Severity Index (DSI) for speech-language pathologist (SLP) decision-making in the evaluation of teachers' voice ...

Environmental assessment using acoustic complexity indicators

Global NEST International Conference on Environmental Science & Technology, 2022
The procedure of sound recording offers new perspectives in ecology. Nevertheless, the existing tools that offer high resolution recordings are expensive. The use of acoustic indicators is proposed as an easy-to-use, rapid, non-intrusive, low-cost option in biodiversity assessment as well as in environmental noise management.

Separation of Cardiopulmonary Acoustic Indicators

2019 Global Medical Engineering Physics Exchanges/ Pan American Health Care Exchanges (GMEPE/PAHCE), 2019
These studies demonstrate a combination of tested methods to separate lung and heart sound signals’ (LS-HS) principal components recorded using a digital dual stethoscope. Initially, when these raw signals are acquired, their principal components intertwine in the characteristics of the frequency and time domains.

Acoustic hit indicator

IEEE Transactions on Aerospace and Electronic Systems, 2001
An improved acoustic target is considered. Acoustic targets estimate the hit coordinates of a supersonic projectile using the time of arrival (TOA) of the supersonic shock wave at several acoustic transducers located in the vicinity of the target. An improved target allows oblique hits, likely in firing practices involving roaming infantry and armor ...

Acoustic and perceptual indicators of emotional stress

The Journal of the Acoustical Society of America, 1983
Tape recordings of telephone conversations of Consolidated Edison’s system operator (SO) and his immediate superior (CSO), beginning an hour before the 1977 New York blackout, were analyzed for indications of psychological stress. (SO was responsible for monitoring and switching power loads within the Con Ed network.) Utterances from the two ...

Exploring the Soundscape in a University Campus: Students’ Perceptions and Eco-Acoustic Indices

Sustainability
Urban noise pollution significantly degrades people’s health and well-being and, furthermore, traditional noise reduction strategies often overlook individual perception differences.

Temporal patterns in Malaysian rainforest soundscapes demonstrated using acoustic indices and deep embeddings trained on time-of-day estimationa).

Journal of the Acoustical Society of America
Rapid urban development impacts the integrity of tropical ecosystems on broad spatiotemporal scales. However, sustained long-term monitoring poses significant challenges, particularly in tropical regions.
