This week, we sat down with Willem Boning, Acoustics Consultant<\/a> at Arup<\/a>\u2019s New York City SoundLab, to uncover the complex relationship between architecture and acoustical treatments. The lesson: Architects must rethink the way that they approach acoustics.<\/p>\n

Rather than selecting an acoustical treatment for its finish, architects must broadly and conceptually think about how they want a space to sound and feel. \u201cWhat excites the Arup SoundLab is to be able to work with an architect or owner to design the sound of a space, not just make it quiet or prevent problems,\u201d Boning said. Should it buzz with excitement or induce serenity so that individuals may independently and quietly work? Seek to tell a narrative with your sound; that\u2019s when Arup\u2019s acousticians can really step in and help.<\/p>\n

The SoundLab was created to help clients make immersive decisions about how much sound-absorbing treatment they should use in a project. Their driving philosophy: The best way to make that decision is \u201cto listen and trust one\u2019s own ears.\u201d Instead of presenting a client with abstract graphs or numbers and exhorting \u201cbelieve us, a 1.2-second reverberation time will work best here,\u201d the innovative approach immerses clients in the potential sound conditions of a future architectural environment.<\/p>\n

It is a container for the real or modeled sound of an alternate place.<\/p>\n

To create a precise simulative environment, the New York City SoundLab harnesses two common yet distinct avenues of acoustic treatment: isolation and absorption. All external noise must be blocked out or \u201cisolated\u201d so that the only sound heard is being played from the speakers inside. Not only is the ceiling designed to block footsteps from above, but the room is built up on a structurally isolated floor, blocking out vibrations from the subway below. While the walls are completely coated in 4 inches of sound-absorbing, rigid duct liner, the wooden floor is only partially covered. As a result, the room\u2019s reverberation time is very short yet just present enough \u201cto prevent you from going crazy.\u201d<\/p>\n

So how does this help architects? Using Ambisonics, an open-source technology, and a process called convolution, the SoundLab allows clients to hear how varying levels of acoustical treatment will affect their final design. To demonstrate this, the acousticians encode a dry anechoic signal with the properties and reverberations of a real room or modeled room. \u201cAnything you listen to in the lab is as if you\u2019re listening in a much larger space. That said, it is still difficult to get a sense of scale and grandeur, which is why we are beginning to work with VR.\u201d<\/p>\n

Located in Monterrey, Mexico, Museo del Acero by Grimshaw Architects<\/a> is one project where sound-absorbing treatment functioned as a focal point of the design. Made out of a former steel plant, the previously echoey space featured extensive hard surfaces such as gypsum board, metal, concrete and glass, only providing space for sound treatment inside the building\u2019s central oculus, yet the client hoped to use the space to host conferences and banquets. By modeling four intensities of sound-absorbing treatment and convolving each with speech, jazz music and techno, the SoundLab led clients to make informed and involved decisions for creating a cost-effective and comfortable event space.<\/p>\n

The SoundLab\u2019s work represents a seminal precedent within a crucial yet unexplored arena of architectural acoustics. The lab guides clients in diving much deeper than viewing acoustic treatment as a material mask to unkind noise. Instead, acoustic conditions are dynamic and possess feedback effects, which ultimately loop back into how people conduct themselves in a particular space: Upon entry, will you speak up or naturally quiet down? And as adaptive reuse becomes increasingly prominent among offices and co-working spaces, this research will prove indispensable.<\/p>\n

Despite breaking all the traditional rules of acoustics, New York City\u2019s Grand Central Terminal rings with a pleasant buzz throughout the day; image via Huffington Post<\/a>.<\/i><\/p>\n

For Boning, \u201cNew York City\u2019s Grand Central Station is a benchmark for a unique soundscape with a pleasant quality.\u201d Offering cues for future open-plan office design, Grand Central is populated, reverberant and filled with conversation yet remarkably easy to focus in. \u201cYou don\u2019t feel like you need to raise your voice\u201d or chime in on any single piece of intelligible speech. At any time of day, you are simply met by a comfortable level of ambient noise. The SoundLab is currently well underway with highly calibrated research that seeks to replicate the qualities of this environment.<\/p>\n

While acoustic treatments are typically marketed as \u201cquieter is always better,\u201d there are no standards or regulations for creating optimal acoustic conditions. Today, it remains a field of experimentation. Sometimes, applying acoustic treatment may feel like tuning an instrument without knowing exactly what key you are seeking to arrive at.<\/p>\n

One of the SoundLab\u2019s end goals is to design a precisely calculated approach; knowing how much of a wall to make sound-absorbing should be like knowing how to build a fa\u00e7ade that blocks out the rain. That equilibrium will inevitably lie somewhere in between \u201csomething is better than nothing\u201d and \u201csometimes, less is more.\u201d Until then, the SoundLab encourages architects to think conceptually and as early on in the design stage as possible about exactly what they are trying to achieve, not just what aesthetic materials they are hoping to employ.<\/p>\n","protected":false},"excerpt":{"rendered":"
