'Headroom' refers to the amount of space between the top of a person's head and the ceiling or other overhead obstruction. It is commonly used in the construction and design of buildings to ensure that there is enough space for people to stand or walk without hitting their heads. It can also be used in audio engineering to describe how much room there is for a sound to increase in volume without distorting or clipping. For example, if someone says they need more headroom for their speakers, they mean they need more space to increase the volume without any distortion.
