Studies are being carried out that suggest that the brain uses vibration (touch) and frequency (sound waves), in a manner that unites these two senses. This means that if a person is good at sensing touch vibrations, then they are also good at hearing sound frequencies — and vice versa. Thus, the senses of touch and sound in architecture are linked, and you as an architect can use this information to make your building designs even better.

I would like to think that architects today are factoring human senses, so that at various points within their design, occupants are invited to use their senses — in a holistic and harmonic way, making architecture greater than the sum of its parts. This is an advantage to designing with the senses in mind, where your architecture can speak to its occupants through different languages and on many levels. And the amazing finding here is that those sensory languages are related to one another in unexpected ways, where your occupants can “feel sound”. (1)

Of course, this immediately highlights the importance of paying attention during design phases to the sound and touch senses (and not solely relying on the visual sense to realize your design vision). Additionally, these findings also illustrate how you should not Read more

We all know that computer technology has done a lot to advance not only the way the design process can work, but also to improve the constructed outcome of that design process.

That’s why I think it’s important to shed some light on what “aural renderings” can do. (1) You, as an architect, can actually listen to a designed space as built to the parameters of your three dimensional CAD model. Here is a detailed description of the process that goes into creating such an aural rendering: Read more

The big challenge for architects designing concert halls is to design the architectural acoustics to meet the needs of varying musical styles. (1)

WHAT YOU CAN LEARN FROM CONCERT HALL DESIGN

The design challenge of a concert hall is at first glance contradictory — to foster closeness and, yet, to surround listeners with the life and essence of a music’s sound.

Different levels of intimacy and aliveness vary depending on music style. What makes this even more difficult is that, intimacy and aliveness are very difficult to quantify — thus, design for. (1)

Such contradictions exist in other architecture types. For instance, hospitals must design to cater to as many patient needs as possible while striving to keep hospital costs low. In office buildings, the need for both individual work and team work is vital – the contradiction surfaces when considering how interconnected the two should be.

SOLVING FOR CONTRADICTIONS

Timing is everything (well, almost.)

A great hospital design could, in fact, help to meet just the right patient needs at just the right time in their healing process. This yields faster recovery and; thus, less hospital cost since patients stay for less time.

The secret is Read more

“HOW WILL THAT SOUND?”

Architectural acoustics are an important part of architectural design. Architects should be asking themselves “how will that sound?” throughout the design process. That is why the tool “LISTEN” has potential to positively impact the architectural design process. By allowing architects to analyze and trial listen to environments, built works can be aurally simulated to hear how they would sound in reality.

BUILDING AN AURAL 3D MODEL

The aural simulation project called “LISTEN” is a simulation for the design of aural environments. By using this tool, architects would be able to Read more

Architectural design requires that acoustics be well thought out and coordinated. The sound spectrum must remain clear without portions distorted or missing. The paper, Acoustics and Sound Systems in Architectural Design, emphasizes how acousticians should be part of the design team early on. The author describes how it is important to avoid overlapping sound waves that project into a common space – this interference is what can distort the sound spectrum.(1)

The following are 7 additional design tips to achieve the best architectural acoustics within a space. These principles highlight some of the most informative ideas found within Acoustics and Sound Systems in Architectural Design for best aural experience.

1) Watch out for SOUND REFLECTIONS. Straight surfaces reflect sounds back into the central space making sound clarity muddy.

2) Select ACOUSTICAL TREATMENT carefully. Different materials absorb sound frequencies differently. Make sure your acoustical treatments are absorbing the right sound frequencies.

3) Diminish ECHOES when necessary. Be aware that sounds traveling within 30 milliseconds of each other are perceived without echo. Sounds traveling after the 30 millisecond threshold become echoes of the original sound.

4) Don’t let other building systems get in the way. NOISE CONTROL is important to keep in check as other building systems (like HVAC systems) operate. Keep such clashing noises to a minimum.

5) Keep objects or other OBSTRUCTIONS out of the way. Objects that obstruct a sound path can block high frequency sounds. (Low frequency sounds can bend around objects.)

6) Get good PATTERN CONTROL. Make sure sound systems for a room get good sound coverage. This will prevent feed-back and other sound distortions.

7) For out-of-the-way listening areas get DISTRIBUTED SOUND SYSTEMS. Such “delay-fill” speakers operate with an electronic delay so the sound matches and is synchronized.

In the end, it is important to make sure that the architectural acoustics match the architectural function and aesthetic value of a particular project. I remember visiting a hospital where the TV sound was obstructed by an HVAC vent. That simple sound collision can make for quite an uncomfortable hospital stay. Similarly, you should make certain that sound travels only when you want it to. Office conversations that needlessly travel to employee office spaces can be quite a distraction.

Involve your acoustician early and coordinate design efforts to avoid uncomfortable and sometimes painful aural sensations. Architectural acoustics are important beyond auditoriums, theaters and religious spaces.
