Audible and Intelligible Notification is Critical for Message Dissemination

Emergency voice communication is dependent on the desired messaging being delivered with a high degree of intelligibility and audibility; e.g., it must be loud enough to be heard and clear enough to be understood.

Emergency voice communication design requires a thorough understanding of audio equipment, acoustics, and applicable codes. JENSEN HUGHES engineers provide the knowledge and experience needed to provide quality design and support services without developing unreasonably complicated systems.

Emergency communication systems encompass both fire alarm and emergency voice alarm communications systems and mass notification systems. The design of these systems requires an intimate understanding of product performance, audio equipment, and acoustics, along with significant experience – all of which JENSEN HUGHES offers.

JENSEN HUGHES has a large number of technical experts capable of providing optimal solutions for audible and intelligible design problems. Providing intelligibility where required while keeping our clients’ needs and economic restrictions in mind sets JENSEN HUGHES apart in the emergency communication design sector.
