Auditory health and sound environments are fundamental but underexplored factors in veterinary medicine. Dogs and cats experience rich soundscapes that profoundly influence their behaviour, stress physiology and quality of life. Yet, hearing loss often goes undetected until advanced stages and stress in veterinary and home settings remains a persistent welfare challenge.

The Pet Acoustics+ App introduces two innovations with transformative potential for veterinary practice: the world’s first mobile, patent-pending hearing test for dogs and cats and subscription-based, scientifically validated species-specific music to reduce stress and improve outcomes. This article reviews the scientific foundations of auditory health in companion animals, it summarises biometric research on sound therapy published in the International Animal Health Journal and evaluates the implications of AI-driven mobile tools for diagnostics.
