Entity FX also had to create the first instance of Clark's super hearing, an ability he acquires in the episode "Whisper". As Beck describes the task: "When you talk about someone flying, it’s something we all know, but this is super hearing and we need to see a visual for the hearing." For the effect of showing Clark using his super hearing, Mat Beck and Entity FX decided that they wanted to travel into Clark's ear and see all the different parts of his eardrum working together to create the sound he is hearing. The task proved difficult to achieve, and Beck asserts that changes will be made to perfect the look of Clark using his super hearing. Clark's super hearing was originally to be revealed early in the season, but when The WB informed the "Smallville" team that Tarzan, the main character in the studio's update of the classic legend, also had super hearing the team decided to delay the introduction so that the ability could be used in a manner that surpassed what was shown on Tarzan. Luckily for "Smallville", The WB's "Tarzan" was canceled before "Whisper" aired, allowing "Smallville" to be the only show on the network with a character who has superhuman hearing.
