Dogs Trust: Masking the sound of fireworks. Part 1: sound design and study preparation

Project Description

Previous research conducted by the University of Salford for the Dogs Trust found that low frequency of fireworks noise is associated with negative behavioural outcomes in dogs. Unwanted noise can be made less perceivable with a masking sound. Masking occurs when the processing of one sound interferes with the processing of another sound in the auditory system, making it less audible. Some sounds have been advertised as helpful to “ease pet anxiety” [4], however it is unclear if these have been proven to improve dogs wellbeing. There have been studies suggesting classical music might have positive effects on animals [5,6], but not much is known about the potential of masking sounds, especially in the context of fireworks noise. This project aims to address this gap in knowledge and aims to further our understanding of how masking sounds can be used to improve dogs’ wellbeing during fireworks season. This proposal describes Part 1 of the project. The goal of this part is to prepare for running a study of masking sounds during fireworks season 2025. This involves designing potential sounds to be used, identifying rehoming centres to involve in the study, and designing a reproduction system which can be implemented in the centres.
