Sound power of onshore wind turbines and its spectral distribution

Sound & Vibration
Wind turbines (WTs) have grown substantially in size and electric capacity over the past decades. The sound power of WTs was reported to increase over time in relation to their electric power and thus over time WTs have become louder.

Three-alternative forced-choice method (3AFC) for tinnitus matching and digital frequency customized relieving sound (DFCRS) generation strategy for tinnitus management

Sound & Vibration
Tinnitus is the perception of sounds without any corresponding external stimulus exists, and it is one of the most common hearing disorders. Currently, there are no objective tests for tinnitus, and thus its detection relies on the subjective reports of ...

CONTROLLING INCIDENT SOUND FIELDS WITH SOURCE ARRAYS IN FREE SPACE AND THROUGH APERTURES

24th International Conference on Sound and Vibration 2017, London Calling
The active control of an incident sound field with an array of secondary sources is a fundamental problem in active control. In this paper the optimal performance of an infinite array of secondary sources in controlling a plane incident sound wave is ...

A COMPUTATIONAL ANALYSIS OF SOUND DIRECTIVITY FROM SOUND PROPAGATION THROUGH NON-ISOTHERMAL, TURBULENT EXHAUST JETS IN CROSS-FLOW

24th International Conference on Sound and Vibration 2017, London Calling
When predicting community noise, it is commonly assumed that the directivity of sound from exhaust stacks is axisymmetric, which is appropriate in the absence of cross-flow.

Sound in sight: audio and sound-focused art exhibitions in New York between 1978 and 1984

Sound Studies
Throughout the 1970s, a drive towards the diversification of mediums available to artists led to artists working across numerous mediums not usually associated with visual art. While some came to work with sound as a central focus in their practice, most
