Success Stories in Acoustics with Émilie Carayol
1/ How can architects collaborate effectively with acousticians to achieve the desired results in terms of acoustics?
Architects and acousticians collaborate effectively by prioritizing volume suitability early on. They integrate architectural intentions with acoustic needs from the outset to ensure seamless integration rather than treating them as separate elements.
2/ What challenges do acousticians encounter when designing for optimal acoustics in various environments and spaces?
Sometimes, integrating necessary acoustic treatments can clash with architectural intentions. We strive to find harmonious solutions, possibly combining acoustics with elements like thermal or lighting aspects, rather than treating them as separate additions, to maintain cohesion in the space.
Architectural Soundscapes with Julian Treasure
1/ What are some innovative approaches, you suggest for transcending traditional norms in architectural acoustics?
Innovative approaches in architectural acoustics involve utilizing new materials to reimagine acoustic design, making spaces both functional and aesthetically pleasing. Additionally, integrating high-quality sound systems tailored to specific environments, such as hospitals, can greatly impact outcomes. Emphasizing the value of sound quality over cost ensures a pleasant auditory experience that complements the overall environment, crucial for attracting people back to spaces like offices.
2/ What is the role of music in creating with acoustics in mind?
Research suggests that a third of the population dislikes music, making it crucial to consider appropriateness, especially in retail settings where upsetting customers can be detrimental. In environments like offices, the appropriateness of music varies depending on tasks and teams. While creative teams may benefit from music as a stimulus, others find it distracting. Biophilic sound, which few object to, can offer a solution. Involving people in sound decisions and offering choice leads to greater acceptance. However, imposing music without consideration can breed resentment, as it often proves as distracting as other noises. Therefore, careful consideration of the space, tasks, and individuals is essential before implementing music in any environment.
3/ How will artificial intelligence affect this industry?
Artificial intelligence, like Suno, is rapidly advancing in music creation, mirroring its impact in text writing. Soon, AI tools may tailor music to suit specific spaces and needs. Properly briefed, AI could control a building's soundscape, enhancing user experience. Overall, AI holds great potential to revolutionize the industry.
4/ Do you think that architects can or will eventually play a greater role in designing the acoustics of spaces thus reducing the need for artificial acoustic treatments?
Architects can play a greater role in designing the acoustics of spaces from the outset, thereby reducing the need for additional acoustic treatments later on. This approach integrates acoustics seamlessly into the building design, enhancing overall sensory experience and well-being. By involving acousticians early in the design process, spaces can be created that naturally sound good, rather than relying on artificial treatments post-construction.
Harmonizing Spaces with Maarten Hornikx
1/ For sound absorption test, apart from impedance tube test and reverberation chamber test. Is there any other test we can do for testing a material's sound absorption?
The two tests you referenced are laboratory tests, and they are widely recognized as the most common and standardized methods. They are effective for quantifying the sound absorption of materials. Additionally, it could be beneficial to conduct measurements in situ, meaning with the material installed in its actual environment. Various methods exist for assessing sound absorption in situ, such as employing devices like the one available at this link: https://www.4silence.com/sonocat-instant-accurate-insight/
2/ What are some common challenges architects face when designing for acoustics, and how can they overcome them?
I believe it's crucial for the architect to integrate acoustics into the design process right from its inception. This can be achieved either by the architect themselves or by involving experts during the initial stages of design. This approach allows for crucial design decisions regarding the dimensions/shapes of rooms, the functionality of spaces, and the primary choice of materials to be carefully considered in relation to acoustics. By addressing typical acoustic challenges early on, such as excessive use of glass resulting in high reverberation times and the occurrence of standing waves or flutter echoes, or open spaces accommodating multiple functions, potential issues can be effectively managed throughout the design process.
3/ How do architects effectively integrate acoustic materials into their designs without compromising aesthetics?
Architects prioritize aesthetics in material choices to align with their vision. However, functionality should be considered foremost in design. If acoustics don't support the intended use of a space, compromising on function might be necessary (e.g., avoiding using an atrium for meetings). Solutions to acoustic issues should be explored without significant compromise, such as applying sound absorption under walkways rather than altering glass walls. Collaboration between architects and acousticians is crucial to discuss material options and spatial zoning to address these challenges effectively.
4/ Is there any known research on needle or wool felting, specifically regarding the differences in composition and hardness between needle felting, which tends to be denser and harder, and handmade felting, which is typically more open and softer?
Typically, needle/wool felt is an open porous material known for its acoustic properties as a sound absorber. The denser the material, the lower its sound absorption capabilities. It's challenging to determine if handmade production results in a difference, but I anticipate that handmade items might have difficulty achieving the high density of industrial production, thus potentially leading to increased sound absorption.
