They had the appropriate Torpedo sound, when the phaser animation shows up, but when the exclusive Torpedo animation, shoots one, they sound nothing like it, smh.
PHASER TURRETS The NCC-1701's Phasers Are Capable Of Firing Very Powerful Pulses Of Supercharged Alien Energy. The Main Phaser Banks, Each Powered By Single Emitter. Are Located Near The Bottom Of The Primary Hull, With Additional Bank's Located On The Ship's Flanks And Stern. Because Phasers Cannot Transcend The Speed Of Light. They Are Only Used When The Enterprise Is At Subwarp.
MAIN TORPEDO LAUNCHER These Alien Missiles Consist Of A Small Amount Of Matter And Antimatter Bound Together In A Magnetic Coil And Encased In A Alien Photon Tube. They Are Powered, Essentially. By Miniature Warp Drives. Unlike Phasers. They Are Not Limited By The Speed Of Light. And Thus Are The Preferred Alien Weapons While The Enterprise Is At Warp Speed.
WARP SPEED Warp Speed Is Achieved By A Controlled Explosion Of Matter And Antimatter Within A Starship's Warp Core. This Explosion Literally Warps The Space Around The Ship, Allowing The Ship To Travel Faster Than The Speed Of Light. Which Itself Has A Warp Factor Of I. Higher Warp Factors Are Computed Geometrically. Not Linearly.
