Converting the historic Pentridge Prison into a boutique hotel presented unique acoustic challenges, particularly regarding noise transfer through original bluestone cell doorways and heritage cell doors.
The DDEG Acoustics team engineered innovative double glazing and sealing solutions, ensuring acoustic performance for luxury suites while preserving the untouched heritage cell doors.
An acoustic consultant assesses, designs and advises on noise and vibration control in buildings and the environment, ensuring spaces are comfortable, safe and compliant.
Acoustic engineering uses advanced modelling, measurement and technical expertise to deliver tailored solutions that go beyond basic noise control, addressing complex challenges in design, construction and operation.
Performance-based acoustic solutions use technical analysis and acoustic engineering principles to achieve compliance when standard noise or vibration criteria cannot be met. Our acoustic consultants design and justify alternative approaches that deliver optimal sound environments and meet regulatory requirements through alternative pathways.
Engage early, ideally at the concept or schematic design stage, to avoid costly redesigns and ensure that acoustic performance is built in from the start.
Yes, we provide practical advice and solutions for refurbishments, retrofits and upgrades to meet current acoustic requirements.
