A great deal of time is spent refining sounds and the sound designers, Foley artists and effects editors who invest in that time should receive a fee.
The main thing you need to make sure of when you are using someone else's material is that you have the written permission.
If a sound effect has been created by someone it is their property and they need the appropriate form of revenue when their materials are being used.
