Spatial hearing
3D audio experience
Audiovisual special effects
The combination of visual impressions, spatial hearing and our imagination creates impressive special effects.
About the video: It is best to watch on a large screen in full screen mode, sit upright and use earphones! Only then can you achieve the greatest possible effect.
The secret
3D audio” or “binaural recordings” refers to special signals that give the ears a realistic spatial impression. Although only stereo is used, our brain can calculate the two slightly different pieces of information from both ears and deduce the exact direction from which the sound is coming.
People can assign 3D auditory events to specific directions. Binaural recordings are stereo signals that can only be reproduced correctly with headphones or earphones. 3D audio is the best technical solution for reproducing a spatial auditory impression realistically. The use of the same technique in music is often referred to as 8D audio. It is more about creating a large sound field than specific special effects. An 8D sound event becomes an auditory event when sound waves reach the brain as a stimulus via the ear.
The ear distorts the 3D signal on its way to the brain. These stimuli are impressions that vary from person to person. Binaural 3D audio recordings can be stored using an “artificial head microphone”. It consists of a head replica with two omnidirectional condenser studio microphones inserted in the artificial head. The first stereo dummy head was built back in 1933.a
The online show
I have already established virtual special effects with my online show. Digital conferences have long been standard in many companies. So why not improve the virtual habits of conference participants with spatial 3D audio effects? The more immersive a digital event can be held, the more likely it is to be a genuine substitute for face-to-face events. The only technical requirement for 3D audio is that the online show is transmitted to the participants in stereo. This happens automatically on YouTube, for example. Zoom requires an extra setting, which results in a higher bit rate.
