In the early days of television, audio was often called, “that noise that accompanies the video.”
That is no longer the case, especially as viewers strive for a more immersive audio experience. Along with improved picture quality, the audio needs as much attention. Viewers are accustomed to DVD-quality audio and broadcasters must strive to match it. In the case of television stations, loudness is a matter of FCC regulations.
And when it comes to monitoring audio, the choices are speakers and headphones. Most engineers understand what is required of speakers, but what about headphones? Do you know how to pick a best pair for an application? We can help.

Audio loudness, or the difference between program-level audio and the commercials eventually caused TV broadcasters a real headache. Because commercials were often highly compressed they sounded louder than the TV programs and viewers complained. In fact, a dinner guest in the home of California Representative Anna Eshoo was so angry about the levels, he asked her to do something about it. That caused her to launch a one-woman petition to the FCC, which was forced to reign in TV audio loudness. Another result was that an entire range of new audio test and measurement equipment was developed to monitor loudness.

Headphones continue to be an important tool for accurate audio monitoring.
Out of the dozens of brands and types of headphones on the market today, how does an audio producer — who wants to monitor “accurate” sound — select the best model for professional use?
For professional sound monitoring purposes — both live and in the studio — the most frequently used headphones are the full-sized, over-ear models, which provide excellent bass response, sound clarity and good isolation from outside noise. The extra padding makes these headphones comfortable to wear, but they are larger than phones made for portable stereo applications.
