The technical program not only integrates sessions on the usual topics of Inter-Noise congresses but also expands to cover specialised areas, including noise control in marine environments and rural and remote areas. Noise that may be barely noticeable in a city environment can become highly disruptive in remote or outback regions, underscoring the importance of different solutions for these unique contexts. Similarly, uncontrolled anthropogenic noise in the oceans and rivers poses a threat to our marine life. We believe it is our collective responsibility to tackle these and other such noise control and related, local and global challenges through meetings like Inter-Noise 2026 Adelaide.
