Architectural acoustics focuses on designing spaces to optimise sound quality and reduce unwanted noise. Key considerations include sound insulation for minimising sound transfer between rooms, particularly in spaces like gyms and auditoria, where acoustic clarity is critical. In studio design, acoustics are tailored to support audio recording and post-production editing. Office acoustics needs to allow for audio visual conferencing and speech privacy, ensuring clear communication and comfort with a growing emphasis on well-being and sustainability. Certifications like BREEAM, WELL, LEED, and SKA guide integrating acoustic solutions in environmentally conscious designs. Effective building isolation techniques address train groundborne noise & vibration and façade design needs to protect from external noise intrusion. At the same time, room acoustics & finishes are carefully selected to enhance the auditory experience and create balanced sound environments.
