Stealth Air Cooled Chiller - delivering the highest combination of part-load and full-load efficiencies and the lowest published sound levels.
High performance schools strive to maintain background sound levels that are ideal for learning. Much of the education that takes place in K-12 education hinges on oral communication, after all.
Experts believe that as many as one-third of all students miss up to 33 percent of the oral communication that occurs in the classroom.1 Children under age 16 lack the knowledge and maturity to correctly infer meaning from missed and misheard words.2
Poor school acoustics create extra challenges for students who are coping with learning disabilities, hindered by impaired hearing or struggling to learn in a non-native language.3
The American National Standards Institute (ANSI) through the Acoustical Society of America (ASA) developed and published the ANSI/ASA S12.60 standard for classrooms and other learning spaces to address acoustical performance criteria and design requirements for schools. Trane proudly supports this organization and offers a free download of the ANSI/ASA standard to anyone who is interested in creating better school acoustics and higher-performing classrooms.
In recent testing, Trane has been able to prove that the ANSI/ASA S12.60 recommended sound levels can be met in new and existing schools buildings with minimal or no added cost using off-the-shelf HVAC equipment and industry-accepted design and construction practices.
When selecting a new system or renovating an existing classroom, the Trane Acoustical Program (TAP™) acoustical analysis software accurately predicts and compares the sound levels of various HVAC system and construction options.
