If It Sounds Like Noise to You, It May Be “Esion”
Fundamentally, sound is “that which we hear”. What we hear at any given time can greatly influence us. We use sound to communicate, to express warning, fear, pleasure and excitement. Some sounds can relax us and help us fall asleep, while other sounds can distract us and make it more difficult to perform simple tasks. Different sounds can be soothing and pleasing or annoying and irritating. Accordingly, determining “What is sound?” and “What is noise?” can become a highly subjective task. As engineers and scientists, it’s our job to generate generalized models that have a high level of correlation to humans (or to specific populations). (more)
Space Savers | Acoustical Engineering for Gymnatoriums and Cafetoriums
It certainly isn’t a new idea… How do we maximize our space and minimize our cost without the loss of function? Surely this is the major driver behind ideas like the gymnatorium or the cafetorium. We’ve all seen them, most likely they were in the schools that we attended. They consist of a stage at one end of the room or tucked away in the corner. So, do these budget savers really work like they are supposed to? (more)
When One Size Does Not Fit All | Diffuser Sound Levels
On a recent trip to India, I discovered a cute clothing sizing term called “free size” which is equivalent to “one size fits all”. Free size clothing must be a manufacturer’s delight since production and distribution are greatly simplified. Adjustments to the size of the garment are typically made through waist ties of various designs and if needed, permanent alterations.
In the A/E/C industry, diffuser, grille and register (air device) manufacturers have chosen the free size philosophy when it comes to providing sound data. (more)
The Varying Acoustical Needs of Churches
Some acoustical environments are straightforward in purpose. A movie theatre, for example, needs to project the sound of the movie with precision and clarity to all seats in the house. Most acoustical environments, however, have varying needs which are dependent on their content and delivery, and the Church is no exception. Today’s churches use a wide variety of forms of aural communication – drama, dance, video, soloists, choirs, the spoken word, and so on. But by far, the two most prominent aural elements in church services are music and the spoken word; two elements that require vastly different (and somewhat conflicting) acoustical environments. Today we will explore the optimal environments for both. (more)
