Final answer:
Mid/high frequencies can also be affected by room acoustics through reflections, diffraction, and absorption of sound waves.
Step-by-step explanation:
Yes, mid/high frequencies can also be affected by room acoustics. While it is true that lower frequencies have longer wavelengths and are more prone to room modes and standing waves, mid/high frequencies can still experience interference and resonance in a room. The behavior of sound waves in a room is influenced by its dimensions, shape, and the materials of the walls, ceiling, and floor. These factors can cause reflections, diffraction, and absorption of sound waves, affecting the distribution and quality of sound in the room.
