7 Design Tips for Best Architectural Acoustics
The science of sound as it pertains to buildings. There are three major branches of architectural acoustics. (1) Room acoustics involves the design of the interior of buildings to project reflected and diffused sound at appropriate levels and time intervals and with appropriate esthetic qualities for music and adequate intelligibility for speech. Room acoustics is an essential component of the design of theaters, concert halls, lecture rooms, classrooms, and churches, among other building types. (2) Noise control or noise management involves the reduction and control of noise between a potentially disturbing sound source and a listener. The walls, floors, ceilings, windows, and doors in buildings reduce sound energy as it travels through them. Sources of disturbing noise may be equipment and people within the building or intruding noise from external sources of sound, such as amplified music, airplanes, or highways. Noise from building services, including heating, ventilating, and air-conditioning systems; lighting systems; communication, voice, and data systems; and electric power systems, must also be controlled so that it does not disturb people using the buildings. (3) The design of sound reinforcement and enhancement systems uses electronic equipment to improve the quality of the sounds heard in rooms.
7 Design Tips for Best Architectural Acoustics
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 acousticswithin 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.

Simple or Keeping it Simple
Simple or Keeping it Simple
Over the past few months, the concepts of stripping back the superfluous, simplifying and pulling apart the true meaning of integrity have been strong personal themes. For many people, there’s a drive to again inspect old patterns that continue to run happily in the background despite years of self-examination. Perhaps under the direction of a new global energy, there’s a sense of being able to lovingly let go of those things that have served us all well on one level, yet have offered excuses to stay small on another.
I came across Don Miguel Ruiz’ “The Four Agreements” the other day and it strongly resonated with this desire to pare back; to simplify; to become more real as a participant in this world and begin operating in a more authentic way.
With these 4 simple tenets, we could literally change the way we as humans operate in this world. How do they resonate with you? Please feel free to share your thoughts, we’d love to hear from you.
As Simple As that
1. Be Impeccable with your Word: Speak with integrity. Say only what you mean. Avoid using the Word to speak against yourself or to gossip about others. Use the power of your Word in the direction of truth and love.
2. Don’t Take Anything Personally: Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions and actions of others, you won’t be the victim of needless suffering.
3. Don’t Make Assumptions: Find the courage to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness and drama. With just this one agreement, you can completely transform your life.
4. Always Do Your Best: Your best is going to change from moment to moment; it will be different when you are healthy as opposed to sick. Under any circumstance, simply do your best, and you will avoid self-judgment, self-abuse, and regret.

Architect Dame Zaha Hadid dies after heart attack
Zaha : By Basel Al Najjar 01-04-2016
Architect Dame Zaha Hadid, whose designs include the London Olympic Aquatic Centre, has died aged 65.
Iraqi-born, this year she was the first woman to receive the Royal Institute of British Architects (Riba) Gold Medal in recognition of her work.
She died following a heart attack on Thursday in a Miami hospital, where she was being treated for bronchitis.
Her designs have been commissioned around the world, including Hong Kong, Germany and Azerbaijan.
Collecting her Gold Medal in February, Dame Zaha said she was proud to have been the first woman to win in her own right.
“We now see more established female architects all the time,” she said.
Since her student days in London at the Architectural Association School of Architecture, Iraqi-British architect Zaha Hadid (born 1950) has been intensely preoccupied with changing our general notions of space – not only in a physical sense, but also socially and culturally. Hadid’s projects are characterized by their dynamic formal qualities of sinuously, curving shapes, or crystallized strata. This sums up as a kind of new Baroque, a sensuous, more vibrant and engaging type of architecture.
Hadid’s projects during the late 1970s and 1980s were marked by a profound understanding of early 20th Century avant-garde artists and architects. In an attempt to redevelop and make relevant again the formal investigations of Russian Constructivism and Italian Futurism, her projects expressed utopian ideals.
Today, Architects create landmarks projects for all types of functional programs. Their buildings are never bland or mundane, but moreover assertive statements of a particular view, that the world may indeed look different. Their efforts have resulted in a staggering almost one thousand projects throughout the globe, in every scale, from urban design schemes to objects and furniture design.
Along with her strong conceptual and historical awareness, nature’s forms and shapes appear as a recurrent source of inspiration for Zaha Hadid’s architecture. It includes attention to physical contexts and landscapes, whether resulting in layered structures or powerful moving lines but also exploring possible interfaces between patterns and construction.
Hadid’s projects – Dubai Business Bay
Zaha Hadid Architects embraced digital drawing early on. This has made the studio able to challenge traditional ways of making architecture. In collaboration with senior office partner Patrik Schumacher, Zaha Hadid has meticulously explored the possibilities of parametric design, allowing for the conception and construction of architecture as seamless flows of energy and matter. Zaha Hadid is the 2004 Pritzker Prize laureate and winner of the Stirling Prize in 2010 and 2011.
A lot of people spend a lifetime trying to understand the world. A few just try to get the world to understand them. Zaha Hadid, perhaps more important than someone who was merely waiting for their time to come, instead witnessed the world adapting to her.
RIP , the Architect Who Showed Us What the Future Looks Like
