Our state-of-the-art Sound Activated Displays are perfect for use in factories, workshops, pubs and nightclubs, to keep your staff and colleagues safe by indicating when hearing protection must be worn.
When hearing protection is needed constantly, our signs show when Personal Protective Equipment can be safely removed.
Spectra's Sound Activated Displays can also be used in quiet locations, such as classrooms, hospitals and libraries. By setting a lower level trigger you can ensure your surroundings remain calm and tranquil.
