Why is sound from a stereo louder in one part of the room and softer in another?

• Sound is louder in parts of the room where the density is greatest. Sound is softer in parts of the room where density is smallest.

• Sound is louder in parts of the room where the density is smallest. Sound is softer in parts of the room where density is greatest.

• Sound is louder in parts of the room where constructive interference occurs and softer in parts where destructive interference occurs.

• Sound is louder in parts of the room where destructive interference occurs and softer in parts where constructive interference occurs.
