TEN-4 Throat Mic & Speaker Amplifier Kit

HomeTEN-4 Throat Mic & Speaker Amplifier Kit

Amplify Your Voice

IASUS Throat Mic Headset solution offers clear vocal communication for wearers of N95 and elastomeric masks, full-face respirators and PPE. Professionals across a diverse range of industries from first responders and medical professionals to retailers and service providers have heeded the call to slow the spread of virus by wearing masks. This simple yet effective measure protects both their health and the community at large, but makes face-to-face, close proximity communication on the job more difficult.

Clear Communication

N95 and elastomeric masks, full-face respirators and other personal protective equipment (PPE) muffle vocalizations, forcing wearers to repeat themselves and strain to hear others. This slows communication and sometimes results in misunderstandings at critical moments. In business, miscommunication can impact contracts, client relations, operational efficiency and the bottom line. On the floor of a hospital emergency room, it can impact lives. Knowing this, some mask wearers choose to temporarily remove their face coverings to ensure clarity when speaking, but that defeats the purpose.

First, consider a standard microphone. Standard microphones are positioned near the mouth in order to pick up and amplify voice airflow pathways. Speech through a mask is inevitably muffled, but airflow impacts volume. Surgical and cloth masks reduce airflow to prevent the spread of aerosols, while PPE, N95 and elastomeric masks restrict airflow to protect the user. As a result, the reduced or restricted airflow cannot be accurately detected by a standard mic.

To get around this problem, the IASUS Throat Mic Headset bypasses airflow as a medium for sound transference altogether. Using an adjustable neck strap, the Headset mic is placed directly in contact with the wearer’s throat where it picks up vibrations from the larynx. These vibrations are converted into audio which is then amplified and projected through a custom portable PA speaker.

This cutting-edge technology improves the safety and clarity of close proximity communication for those who are working to keep our economies and essential services afloat. The Headset enables wearers of surgical and standard cloth or disposable masks to be heard clearly without raising their voice, which reduces the build-up of moisture within the mask allowing for extended use. More importantly, it ensures that those wearing more restrictive PPE, N95, and elastomeric masks can be properly understood.
