- Conferencing / Installed Sound
The narrow usable portion of a conventional microphone’s polar response (with full frequency response) provides only a narrow area that will pick up sounds without high frequency losses at the sides of the microphone. The figures on the left indicate how many conventional microphones it takes to cover a room (with an 8 foot ceiling) and provide the full frequency response of the microphone at the head of a six foot man, in standing position.
The figure on the right shows the much wider polar response (with full frequency response) of Earthworks directional High Definition Microphones™, requiring fewer microphones. In addition you also have more sound level before feedback, no spotlighting or highlighting, more rejection of sounds from the rear of the microphone, in addition to a vastly superior sound quality.

IMR Data Sheet
Great consistent coverage and a clean, natural, and transparent sound as I have come to expect from the Earthworks product. It makes good audio easy.
They just simply work, and do so better than any other ceiling mics we’ve encountered. The biggest difference is the pickup pattern and coverage area.
The audio quality was superior to other ceiling microphones we’d used for conferencing applications. Improved clarity, appropriate pickup patterns and fewer issues with distance from microphone to participant were some of the key improvements with the Earthworks IM3-W microphones.
