In a recent interview, Evan Buehler, Bungie's head of audio, said that working from home presents new challenges to their work, so they use items commonly found in their homes to make audio, such as ingredients.

For example, the grenade launcher parasite in Destiny 2, Evan Buehler said that macaroni players may find the sound of the weapon familiar, and part of its sound effect actually comes from the sound of beef macaroni and cheese mixing.
Evan Buehler says that when asked how the game's sound is made, they usually show others how the bugs' sounds are made. Some of them will be voiced by voice actors, and then a lot of audio processing will be required to make the sound as they want it to be, only then will the sound of the game become interesting and memorable.
