Acoustics 2.0: Harmonising Sound and People

The synergy between architectural acoustics, passive acoustics, and the innovative solutions of personalised soundscaping technology is set to disrupt the future of acoustics for the better. Kyriakos Papanagiotou, Founder and Director of acoustics consultancy KP Acoustics Group, discusses how we can combine premium architectural design with the highest level of acoustic comfort across the built environment through targeted tech-based solutions.

Over the past century, architecture has continuously evolved, driven by technological advancements through the continuous amalgamation of ideas and methods. Similarly, acoustics has seen a spectacular acceleration, breaking barriers between sound and people.

Today, we stand at a unique juncture where these fields can synergise like never before. Architectural acoustics is transforming buildings across all sectors from hospitals to hospitality. At KP Acoustics Group, we stand at the forefront of this innovation and are leading the way to redefine architectural acoustics. Are you ready for Acoustics 2.0?

The Foundation: ‘Passive’ Acoustics

To understand the change that is driving Acoustics 2.0, it’s important to reflect on the foundations of classic, ‘passive’ acoustics. Traditionally this has relied on the strategic use of materials and architectural design to tame sound, and involves the following techniques:

Sound absorption: Using materials to increase acoustic absorption and reduce reverberation.
Sound insulation: Incorporating proprietary materials and implementing techniques such as acoustic decoupling to prevent sound transmission from one space to another.
Architectural design: Designing spaces with acoustics in mind, including the shape and layout of rooms to optimise sound quality and reduce noise.

These methods have been instrumental in creating acoustically pleasant environments, from concert halls to recording studios. However, passive acoustics has limitations, especially within dynamic spaces.

The Evolution: Intelligent Sound and Personalised Soundscaping

To transcend the limits of passive acoustics, we propose integrating intelligent sound through personalised soundscaping. This approach views sound not just as a highly measurable entity but as an element to enhance the existing soundscape of any environment so that it is affective.

Personalised soundscaping offers significant advantages, allowing users to adjust their acoustic ambience according to their comfort through a tailored experience, and effectively masking specific unwanted noises through targeted tech-based solutions. It also provides control of sound masking settings that adapt to different environments and activities flexibly and creates a more comfortable and productive environment by reducing distractions and increasing privacy, particularly in open office spaces.

Acoustics 2.0: The Synergy

The integration of personalised soundscapes with passive acoustics creates an exciting dynamic that we refer to as Acoustics 2.0. It presents a comprehensive approach to sound management through enhanced noise control, dynamic adaptation, aesthetic and functional integration, and personalised environments. By combining absorption and insulation with personalised soundscapes for enhanced noise control, we can create a balanced auditory environment through innovative architectural acoustic solutions.

These adaptive soundscapes respond in real-time to environmental changes, merging noise control with pleasant auditory experiences in public spaces. For example, within healthcare settings, sound-absorbing materials can create a quieter environment, while adaptive soundscapes can respond to noise levels and patient needs, providing calming sounds during high-stress periods or enhancing privacy in patient rooms.

Additionally, Acoustics 2.0 allows for highly customisable sound environments in homes, tailored to individual preferences and offering both aesthetic and functional benefits. In homes, sound insulation-based design can provide a baseline of tranquillity, while personalised soundscapes can cater to individual preferences, such as creating a serene reading nook or a lively kitchen ambience.

Applications Across Sectors

The potential applications of Acoustics 2.0 are vast, touching various aspects of daily life and industry:

Urban planning: Reducing noise pollution with integrated soundscapes. For example, integrating sound-absorbing materials in construction and utilising immersive soundscapes in parks and public transport hubs can reduce urban noise pollution and enhance the quality of life for residents.
Healthcare: Combining noise control with therapeutic soundscapes for healing environments. Here, sound-absorbing materials can reduce noise from medical equipment, while immersive soundscapes can provide soothing sounds that aid in patient recovery.
Education: Enhancing learning environments with adaptive soundscapes. Classrooms can be designed to minimise external noise and excess reverberation, while soundscapes can help maintain a conducive atmosphere for concentration and learning.
Entertainment and hospitality: Combining ‘passive’ acoustic design and personalised soundscaping can ensure a quiet, comfortable environment while setting the desired mood, from relaxing dinner music to immersive theatrical effects.

Future Prospects

Innovations in architectural acoustics are set to improve our experiences of the built environment – with educational and productivity soundscapes, community sound planning and therapeutic soundscapes for stress and insomnia relief. In the evolving landscape of acoustics, the convergence of passive acoustics with personalised soundscaping technology heralds a new era: Acoustics 2.0. And, as technology advances, the integration of passive acoustics and immersive soundscapes will become increasingly seamless and sophisticated:

Smart building materials: Innovations in materials that not only absorb sound but also integrate with digital sound systems to enhance their effectiveness.
AI-driven sound management: Advanced AI systems that can predict and adapt soundscapes based on user behaviour and environmental changes.
Wearable sound technology (Hearables): Devices that allow personalised sound environments on the go, adapting to different acoustic settings in real-time.

When it comes to Acoustics 2.0, the possibilities are seemingly endless. We’re already seeing a fascinating variety of methods that combine passive acoustics with personalised soundscapes. From ambient sound masking with natural elements and directional loudspeakers for localised audio to virtual window soundscapes and binaural recordings for relaxation.
