To precision calculate the speech transmission index (STI), it is necessary to know the level and spectrum of the interfering noise. Simplified design methods used in public address systems are limited to obtaining an appropriate signal-to-noise rati

Knowledge of interfering noise is necessary for the correct design of a public address system. Noise sound levels can be obtained, for example, from BS 5389-1. It is more difficult to acquire knowledge of the interfering noise spectra, and the spectr

Understanding the impact of room acoustics on non-native listeners is crucial, particularly in standardized English as a foreign language (EFL) proficiency testing environments. This study aims to elucidate how acoustics influence test scores, consid

Adding occupants to an enclosed space often leads to perceptible changes in the sound field and, therefore, speech intelligibility; however, this issue has not yet been examined in automotive cabins. This study investigated the effect of occupants in

A novel 3(Rc)PU parallel mechanism based on the reconfigurable circular groove cross joint (Rc joint) is proposed. The motion branch transformation relationship and constraint performance evaluation method for the mechanism are studied. According to
