Business and Entertainment Audio: Why the Difference?

According to Dr. Mike Hollier, Vice President, Voice Solutions at Dolby Laboratories, advancements in the telecommunications industry have focused on going “smaller and faster.” This quest for more mobile, fully-capable devices came at a cost to the quality of the audio experience, however. In fact, this innovation gap is so vast that Hollier compares today’s business video and audio call quality to that of the decades-old rotary phone (developed in the 1940s). We expect exceptional audio when we go to the movies, so why aren’t video and audio conferencing meeting the same standards? Dolby Laboratories has emphatically answered this question by bringing Dolby spatial audio into the workplace.

Spatial Audio: Natural Conversations with Dolby Digital

Subtle elements in the way we speak convey specific details that are imparted to our colleagues during video meetings and audio conference calls. Circumstances such as who is speaking and who is waiting to speak are crucial indicators that help drive an effective, mutually beneficial meeting environment. While not necessarily visible, these cues are essential to natural communication and make a big difference when picked up by Dolby digital and heard through Dolby spatial audio.

Binaural Audio: How Dolby Spatial Audio Works

The human brain is equipped with an extremely complex set of faculties, a primary one being binaural audio. In prehistoric times, this physiological adaptation was the difference between life and death, as it allowed humans to make ‘flight or fight’ decisions based on what sounds they could pick up - was it a predator or prey? Similarly, spatial audio disperses sound in ways that allow your brain to pick up and differentiate between speakers and other noises. Our brains can selectively isolate the conversations or noises, even in challenging audio situations, because of this high fidelity sound—but it’s not easy. Having examined typical conference calls, Dolby Laboratories discovered this sound fidelity is low because this audio information is channeled into just one ear versus two (which is binaural sound). It’s hardly surprising, then, that an audio conference call can leave you feeling strangely exhausted: your brain was working overtime to try and figure out complex auditory tasks that happen with ease during face-to-face communication. 

Dolby Laboratories: Pioneers in Digital Audio

Imagine how the lack of being able to discern different voices affects a meeting: are you wondering which coworker or client is speaking? It can be embarrassing, not to mention a drain on time, to repeat questions during an audio conferencing call. Dolby Voice and Dolby digital technology reintroduces the natural auditory cues of face-to-face, in-person communication, facilitating a “more natural, multidimensional sonic environment based on the science of how humans hear.”
