Counter-Strike: Global Offensive update for 25 October 2017

Via CS:GO Blog:

SOUND

• Added a new audio occlusion model for CS:GO (disabled by default). This new occlusion model much more realistically simulates the occlusion of sounds that have to travel through and around materials to reach the player. Instead of simply adjusting the volume of sounds that are occluded, this new model distorts the sounds according to the properties of the materials that the sound has to travel through. Eventually we intend to turn this feature on for all users, but at the moment it can be controlled by the convar snd_occlusion. Use snd_occlusion to turn this new feature on. Feedback on it is welcome.
• Fixed a bug where some sounds would play multiple times when observing.
