Tim Vear
Tim Vear
Senior Applications Engineer - Shure

Tim is a native of the south side of Chicago (Go White Sox!). A lifelong interest in both entertainment and science has led to the field of audio as his choice for combining these interests in a useful way. Prior to joining Shure he worked as an engineer for recording, radio and live sound, operated his own recording studio and sound company, and continues to play music professionally. He holds a BS degree in Aeronautical and Astronautical Engineering, with a minor in Electrical Engineering, from the University of Illinois, Urbana-Champaign. While at the University, Tim also worked as chief technician with both the Speech and Hearing Science and Linguistics departments. 

Since joining Shure in 1984, Tim has served in a technical support and training capacity for several departments. He has been active in product and applications education for Shure customers, dealers, and installers, as well as company staff. His major goal has been to increase the understanding of quality audio by presenting technical information in a way that is thorough but still very accessible. Tim’s particular emphasis is on the contribution of proper selection and technique for both wired and wireless microphones. 

In addition, Tim has done technical presentations for many industry organizations (NAB, NAMM, AES, and SBE), as well as for US government entities such as the White House Communication Agency and the US Air Force. Through his international assignments he has been fortunate to be able to deliver presentations in more than twenty countries and on all but one of the continents (still waiting for an offer from Antarctica…). He has provided specific applications assistance to various performing artists including the Rolling Stones and U2 and for theme parks such as Disney and Universal Studios.

While at Shure, Tim has authored several educational booklets including “Selection and Operation of Wireless Microphone Systems” and “Audio Systems Guide for Houses of Worship.”
