In order to make the film the most realistic sound effects, the sound effects team collected real sounds in reality as much as possible. Gunfighting is an important part of the film. The sounds of AK47, bazooka, grenades, etc. are all recorded with real guns. There is also a scene during the launch of the space shuttle in the film. The sound effects team specially went to the military base to record the sound of the rocket launch.
There are many voices that are not universal in reality, and they are realized through various whimsical ideas. The sound of the alien spacecraft invading the earth in the film is made with an electric guitar. The guitarist twists the guitar strings and then processes them through a distortion effect device.
The sound of an alien spacecraft falling on the moon in the film was recorded with dry ice and metal. The sound effects crew made a 10-meter-long hollowed-out long box out of metal. The resonance produced by the melting of dry ice on the metal made a "very space sound". The sound of the collapse of reinforced concrete in the film is the sound formed by the melting of a 40-pound block of ice.
In the dubbing of the Chicago Parachute Operation, the sound effects engineers carefully studied the sounds that the characters could feel during the landing process, and carefully restored the sound of the wind in the ears of the person during the parachute landing.
Most of the robots in the film are voiced by Hollywood actors. Most of the voice of "Megatron" comes from the voice actor Hugo Weaving. In order to make the sound of "Megatron" sound more wild, sound effects engineers made a special trip to the zoo to find inspiration. Finally, a tiger with emphysema in the zoo aroused their interest, and Megatron's crazy gasp in the film came from this tiger.
The sound of "Shockwave" in the film when it destroys streets and buildings with an electric drill is actually a cry from a baboon.
From cartoons to movies, the voice actor of the English version of "Sonic" has always been Frank Wilk. Sound effects director Etahn Van der Ryn said that in order to show the scene of attacking the heroine outside the car, Frank Wilk even pierced himself to scream, and finally got a real on-site effect.
