What impact does mass weighting have on frequency transmission?

Mass weighting influences the way sound frequencies are transmitted through mediums, and it plays a significant role in how different frequencies propagate. When mass is added to a system, it affects the overall stiffness and inertia of that system, leading to changes in how sound waves are transmitted.

In particular, mass weighting impacts all frequencies because it alters the mechanical properties of the medium through which the sound travels. For example, in the case of the ear, adding weight to the basilar membrane will affect how different frequency components are perceived. Heavier membranes can impede the transmission of higher frequencies while also influencing lower frequencies due to the interconnected nature of sound transmission mechanics. This mass-loading effect means that all frequencies can be affected in their transmission, but the degree of impact can vary based on the frequency itself.

This principle also applies broadly to various systems beyond hearing, such as musical instruments or architectural acoustics, where mass influences sound quality and frequency response. Thus, the correct answer recognizes the comprehensive effect that mass weighting has on the transmission of frequency across the board.
