Sound Like a Pro in Virtual Reality Applications

Sound is crucial for creating an immersive experience in Virtual Reality. Just like in movies and series, when there’s no sound, we often expect something startling to happen, because silence creates tension and makes us feel uneasy. The same applies to Virtual Reality: users are focused on their tasks, but if they’re hearing sounds from outside their virtual world without being able to see what’s causing them, it can be distracting and take away from the experience. So, can users fully concentrate on the tasks at hand, or will they be pulled out of the moment? 

Let’s go over a list of tips to master sound design for Virtual Reality experiences! 

• 3D Everything (Even the Sound): Sound shouldn’t be flat or two-dimensional when we have a third dimension to play with: depth! If an object is far away, make the sound feel distant too. Position the sound in a way that matches where the object is in the virtual space. This small detail makes a big difference in creating an immersive experience.
• Sound in the Details: Users appreciate the little things. Creating a realistic environment requires attention to detail, and this includes sound. Make sure everything has an audio cue — from doors creaking to objects colliding. The more precise and nuanced your sound design, the more immersive the experience.
• Mind the Volume: Users might feel a bit disoriented in a new Virtual Reality environment, so don’t make it worse by blasting the volume. Reserve louder sounds for the most important elements and keep background noises at a comfortable level. Also, adjust the volume based on how close or far the user is from the sound source.
• Sounds as Rewards: Use sounds to reinforce positive (or negative) actions. When users perform well, reward them with satisfying sound effects, and when they make mistakes, give them cues with different audio signals. This makes the application more engaging and helps guide user behavior.
• Realism Matters: The level of realism in sound is crucial. If your Virtual Reality objects are cartoonish, and the sounds are hyper-realistic, it can create a jarring and inconsistent experience. Make sure the style of the sounds matches the visual style of the environment for a cohesive and believable virtual world.
• Speak Up: In Virtual Reality, reading text can be uncomfortable, so it’s better to use voiceovers to convey information. If you must include text, make sure there’s an option to have it read aloud. Let users choose whether they want to read or listen to the information.
• Record Clearly: Pay close attention to the quality of your recordings. Since you’re using a 3D sound system, clarity is key. If a user teleports or moves around, they might miss certain parts of the audio, so plan accordingly. Consider programming actions to account for these situations, like repeating key messages or adjusting the sound settings based on the user’s position.
• Ambient Soundscapes: Create a consistent ambient background sound to set the mood of the environment. This could be anything from the gentle hum of a spaceship to the distant chatter of a busy city. Ambient soundscapes help fill the silent gaps and make the virtual world feel alive and dynamic. Just make sure these sounds are subtle and not overwhelming.
• Customizable Audio Settings: Not all users experience sounds the same way, and some might find certain noises uncomfortable or too loud. Include audio settings that allow users to adjust volume levels, mute specific sounds, or even change the balance between music, effects, and dialogue. This enhances accessibility and user comfort.
