Audio in Broadcasting Learn why sound is more important than you think – Aswin Vijayaraghavan

Most of the websites and apps we use today include some form of video. The medium has become so ubiquitous that you can learn about almost any topic in the world through them. However, visuals in videos need significant accompaniment to make them a great way to access information, i.e. they need sound. Without rich audio, visual learning remains incomplete.

Let’s try a simple thought experiment to understand the role of sound in learning. If you watch a slice of bread toasting on a pan, can you guess how hot the pan is if the video is muted? Or if you watch a movie with a steam engine rolling along a track, can you guess how far it is from the destination if you don’t hear the train horn getting louder? The sizzle of the pan and the sound of the train are as important in helping us understand the context as the visuals we see. For any type of visual learning, the auditory element becomes important to complete the picture.

Sound is an essential part of how we learn. Without it, most educational communications can fall flat. But when used correctly, it can make learning more engaging and intuitive for the learner.

The cognitive role of sound in learning

Although each sense plays a key role in learning about and interpreting the world, “sound” is often overlooked because it is not tangible. However, while learning new information, sound becomes a great resource to help us add context.

According to scientists, you hear things 20 to 100 times faster than you see them. The brain’s auditory circuits are also connected to areas associated with basic functions, including emotion. This is why sound, or rather music, to a large extent can generate specific emotional responses. These properties of sound and music, combined with realistic visuals, can make learning more impactful and memorable.

“Sound” learning needs audio

Sound is one of the first things we grasp and learn. Young children can often be seen bouncing or clapping in response to music long before they can speak. Several studies have also shown that music helps in language acquisition.

One study, in particular, noted that parts of the brain associated with language development, speech perception, and reading skills all grew faster when children received musical instruction. Sound-rich activities, such as playing an instrument or speaking two languages, have also been shown to have a positive impact on attention spans. Reading aloud to children and verbal storytelling also play an important role in memory and vocabulary development.

The pace of audio-visual learning

While creating learning content at BYJU’S, incorporating good sound into our visual media has been an integral goal. Most of our videos have verbal narration that complements the visual explanation of concepts. For our young learners, most concepts are explained through at least one song that brings a musical element to their learning.

In addition, our large team of sound designers composes, mixes and masters the soundtracks of all our products. Multiple teams perform each of these processes in sync. Over time, we’ve found that taking a different approach for different age groups and topics can make learning more engaging for them. For example, in a subject like social studies that students sometimes find boring, using cinematic soundscapes to bring the story to life plays a big role in engagement.

Our teams mix together different genres of music, crossing different instruments and styles, to create the right audio tracks for our animated videos. Sometimes it goes beyond studio work to stepping into the world and capturing moods, or background sounds, that make different settings look realistic. Everything you hear in a BYJU’S video is placed there as precisely as what you see.

“Audio” in audio-visual learning can be vital to creating positive learning outcomes. With technology-enabled learning reaching more students every day, there are plenty of opportunities to create rich visual learning experiences powered by sound.
