April 2023 Newsletter: Selective Auditory Attention: How Our Brain Keeps Us Focused

Have you ever been so engrossed reading something that you didn’t hear someone talking to you? Or hard at work while listening to music and suddenly realize you weren’t really listening for the last few minutes?

This phenomenon is known as selective auditory attention and is a topic that falls within the broader subject of psychoacoustics.

November 2022 Newsletter: Classroom Acoustics now Code Protected!

An acoustic environment that is conducive to learning requires low ambient sound levels and a high degree of speech intelligibility. Prior to 2021, unless a school was pursuing LEED or had adopted ANSI S12.60-2010 Acoustical Performance Criteria, Design Requirement, and Guidelines for Schools, classroom acoustics were guidelines, not requirements. That all changed with the 2021 International Building Code (IBC) which has incorporated Enhanced Acoustics for Classrooms criteria. Read on to brush up on the new requirements as more schools and states begin to adopt the most recent IBC.
