Common questions
Frequently asked questions
Why does classroom sound matter?
Students have to hear the teacher clearly to learn. Groups like ASHA point to background noise and reverberation as barriers to listening in classrooms, and the ANSI/ASA S12.60 standard sets acoustic targets for core learning spaces. Classroom audio helps keep the teacher's voice clear in every seat.
Portable voice amplifier or a classroom audio system?
A portable amplifier helps one teacher in one spot. An installed classroom audio system spreads the teacher's voice evenly through the room and can tie into panels and other sources. The right choice depends on the room and how it's used. How Haddock helps: We can assess a few rooms and recommend options.
