  • Classroom Speakers

    Cetacea is best known for its omni-directional acoustics (patent) which solves the problem of unbalanced audio, particularly in the vocal range, for group listening applications in K12, Higher Ed, and other training spaces. Only one speaker is needed for a standard sized classroom.

  • Classroom Voice Amplification

    Classroom voice amplification, sometimes referred to as "voice lift", is the addition of a wireless microphone and speaker-amplifier system to a classroom. The goal is to raise the speech level of the teacher to give students an equal opportunity to comprehend instruction, no matter where they're seated.

  • Teacher Microphone

    In very few markets other than education, vocal instruction is provided for 6+ hours a day. A system like the Orbiter teacher microphone relieves vocal strain for teachers while also benefiting students with increased vocal levels in the classroom.
