Did you know, that according to, an ice-cream cone was used to produce the sound of raptors hatching in the film, Jurassic Park? Or that jelly, popcorn and liver were used to create the sound of ET’s movement in the film of the same name?

Auditory input is integral to most films, so too is it an important part of learning and teaching. It helps explain learning content and express emotion. However, for some learners, processing auditory information is challenging or impractical. Challenges may stem from hearing impairment, competing sources of auditory information (eg background noise, multiple people speaking at the same time, music, etc), the location of the learner (eg on the train), the time it takes to process auditory information or even difficulties with memory, so here is some sound advice!

Practical Strategies

Awareness of these potential barriers allows educators to provide alternatives or supplements to auditory information. Captioning videos is a relatively simple way to allow an alternative to auditory information. Speech-to-text options also serve this purpose. Transcripts of lessons or seminars provide an alternative, too.

To supplement auditory information, enhance learning with visuals. These may include posters, infographics, diagrams, illustrations, photos or notations of music and other sounds. Making use of symbols and emoticons to supplement auditory information is another option. Where required, sign language and braille options must be considered.

Other visual and tactile information serves to supplement auditory information, too. Consider the ‘yellow line’ on a train platform. In addition to announcements over the intercom to stand behind the yellow line, train stations have signage sharing the message and tactile ground surface indicators (the rows of slightly raised circular markers). The provision of auditory, visual and tactile messaging serves to reduce barriers to understanding.
