285. Instructional Audio for Equitable Classrooms with David Solomon
In this episode of Learning Unboxed, we welcome David Solomon, CEO of Lightspeed Technologies, to unpack “instructional audio”—low-volume, high-clarity sound that makes the teacher’s voice equally intelligible in every seat. We explore why clarity beats volume for attention, language development, and early learners, and how speaking in a natural tone calms the room and boosts comprehension.
We also dig into real-world use: integrating classroom audio with displays, computers, PA, and security so pages and emergencies cut through, and teachers can route any audio evenly across the room. David shares quick-win adoption tips—from simple in-class demos to funding paths like bond measures, Title I, and local foundations—and how Lightspeed’s Activate tool supports small-group instruction by letting teachers listen in and jump in at the right moment.
