We see the use of acoustic tile in large spaces to thermally insulate the structure and to absorb sound. Generally speaking, any acoustic medium that is installed to cut reflected sound (echo) is going to reduce all sound and not "undesirable" sound. But we know that the planned use of acoustic tiles will allow us to make a space that is very "sound friendly" and that can be very useful. Many people can pack into this space and all of them will have a relatively "good" listening experience. The "message" will be carried throughout the space without a lot of detracting reflections.

Pleasant sounds are nice to hear and unpleasant sounds are not nice to hear.
Low pitched sounds have a low frequency. Higher sounds have high frequency, that is the number of waves passing a point per second is greater.

That sounds as if you want to stop using energy. That's not possible - we need energy to survive. We (humans) can reduce our use of energy, and we can try to reduce the environmental impact of the energy we do use.
The person's lungs are not moving air well in emphysema. Also irritants cause increased production of phlegm, which can reduce air movement, hence, diminished breath sounds.
Most animals and insects reduce their competition by showing aggression or power in their area. There are sounds they make to warn competitors and other signs to keep them away.

Occasionally in major cities like Chernogorsk the bells in churches will ring. This is merely an ambient sound and has no effect on gameplay beyond masking sounds like footsteps and gunshots.
The sounds of nature, such as birds chirping, rustling leaves, or flowing water, can have a calming and soothing effect on our mood. These natural sounds have been shown to reduce stress, anxiety, and improve overall well-being by creating a sense of relaxation and connection to the natural world. They can also help us feel more grounded and present in the moment.
