Our Visual Focus (part 3) – Deafly Designed

What do modern human societies sound like? Have we neglected the soundscapes of human society, and how may our cultural focus on our sense of sight have affected how we design buildings?

The World Health Organization (WHO) categorize noise as the most significant environmental health threat right after air pollution (1). This should also be seen in the context of the world population becoming increasingly concentrated in cities while spending upwards of 90 % of their time indoors (2) and that for example about 70 % of all office workers find that their sound environment does not support their activities (3). So what exactly has gone wrong in our way of designing modern human habitats, and how can we begin to move in the right direction?

In part 1 & part 2 on this topic we delved into the cultural roots of our visual focus and how the claims of the supremacy of vision might very well be overrated. In this post we will examine how ‘ocularcentrism’ (or visual orientation) affects building design in the professional field of architecture. For acousticians and sound enthusiasts the under prioritization of sound and acoustics in architecture is nothing new (4), but to move closer to a more complete and holistic approach in this domain we must first understand the problem on a fundamental level.

Architects and designers tend to focus exclusively on (the eyes). They use these to design with and they design for them.” – Julian Treasure.

Most people would tend to describe building design as a visual artform, when in reality it is experienced by all the senses.

Visual focus in architectural design

As an example of a deeper look into this issue, the book “Eyes of the Skin” by Juhani Palasmaa explores how the visual focus in the field of architecture neglects other sensory domains. This does not only raise a concern that what cannot be seen will have a natural tendency for being overlooked, but also implies that visual qualities will be excessively overvalued compared to non-visual aspects.

As such acoustics is an example of an invisible quality of buildings that is easily under prioritized and undervalued.

A bit oversimplified, we can describe architectural design, like other fields of design, as essentially being about giving shape to something new. The longer the process goes on the more concretized and static the design becomes. To ensure that a given design is going to accommodate the intended use and environment, it is crucial that the designer have a holistic understanding  of the hierarchy of qualities that her creation should be shaped around, from the very beginning.

And in this way, considerations about acoustics are typically pushed to the later stages of the design phase, at which point a lot of the design is already finalized and ‘locked.’ In this way acoustic design will often suffer from reduced possibilities in terms of everything from time, materials, geometry, physical space, aesthetics just to name a few. In the worst cases, this means that the acoustics of the final buildings will be unsatisfactory or even intolerable to its users. At this point, an acoustic renovation (5) will be costly and have to be “shoehorned” into the existing design, which ironically rarely creates a visually pleasing aesthetic result.

Finish architect and author, Juhani Pallasmaa.

I believe that many aspects of the pathology of everyday architecture today can (…) be understood through an analysis of the epistemology of the senses, and a critique of the ocular bias of our culture at large, and of architecture in particular.” – Juhani Pallasmaa (6)

Knowledge and creative possibilities

But even if architects are convinced of the importance of good acoustics they might not be able to incorporate it their designs. You might even say that traditional architectural design is ill equipped to even incorporate acoustic design in the design process. Typical architectural representational tools, like sketches, plan drawings and even renderings do not inherently invite any considerations of acoustics as opposed to space, geometry, lighting etc. Buildings materials or solutions may have the exact same superficial look, but completely different acoustic qualities.

This is why it is often said that architects should learn to design with their ears (7). This counter-intuitive and a bit quirky statement, basically entails a conceptual leap of understanding. It means that architects must have a fundamental theoretical or practical understanding of how geometry, materials, people and sound interact if they are to create good sounding buildings. Because it is not an automatic or intuitive consideration of their tradition or tools, it has to be so well integrated into their approach that it becomes incorporated in any design from the beginning of the design phase.

Acoustic knowledge can in this way be categorized as what is known as a positive design constraint (8) that creates a more accessible array of creative possibilities and ensures that the design process is aligned with a more sustainable result in terms of accommodating its users from the very beginning.

In spite of rigorous research, acoustics often receive little attention by architects.

Symptoms of ocularcentrism

Unfortunately, we don’t have to search particularly hard to find the effects of the visual bias in architectural design. Recent architectural history is full of costly, high profile construction projects that were built without somebody ever seriously raising the issue of acoustics. What is even more egregious is that some of these buildings actually win architectural awards. On Acoustic Bulletin we have covered the negative effects of bad acoustics thoroughly, but how do the symptoms of this visual bias within architects appear in the physical building?

Typically, architects have an affinity for hard, smooth surfaces and cubistic geometry. This creates very reverberant spaces where sound energy builds up and noise levels escalate.

Furthermore, their infatuation with light and views has given them an affinity for larger rooms and opening spaces up and connecting rooms. Larger rooms likewise prolong reverberation if not treated with the right acoustic materials and adds to noise levels. Open spaces naturally do not only transmit light, but also disturbing noise. While open spaces with great acoustics can indeed be successfully created, it takes even more careful design attention to design these well.

While variety and harmony is both prized and carefully composed by architects across various visual elements such as shape, texture and detail, the same level of consideration is not applied to the invisible element of sound. This often leaves the acoustic quality of spaces “flat”, monotonous and ill-suited to an environments particular function.

Another type of mistake arises due to misunderstanding of the nature of sound and/or quality of acoustic materials. This could be by choosing acoustic materials of low quality, installing them incorrectly or expecting very small amounts of acoustic material to have an effect on a very large area. Examples of these mistakes could be paper thin curtains installed to create speech privacy, meeting rooms for important conversations without  adequate sound isolation, or a small cluster of acoustic furniture in the middle of a huge reverberant space to reduce noise levels.

Thin curtains are often utilized as acoustic treatment with little to no effect

How will the future sound?

Luckily, the future of the architectural and construction industry will create a much better sounding world. Acoustics are gradually being taking seriously, written into law and buildings codes, adequately specified within the design brief of a new building and taught in architecture schools. Ecophon has always been on the cutting edge of this development and continues to push this process along. At Ecophon, we have developed a long list of tools from design guides, teaching materials, calculators, design methodologies and much more to support knowledge of acoustic design to be spread all over the world – and more is to come.

Most of the content of this post is based on the experience of the authors. Morten Roar Berg wrote his master’s thesis on implementation of acoustic design in the field of architecture and worked as an acoustic designer at the architecture firm Bjarke Ingels Group in Denmark. Lauren Clark uses her background in Interior architecture together with a fascination in the invisible elements of design to challenge and propose how spaces can be designed and used better, particularly in emerging markets. In their daily work they both help architects and designers integrate acoustic design in their work.
