Chimpanzees have been observed to make music-like sounds in the wild, and some researchers believe that like our ancient hominin ancestors, they may have an innate musicality. Although chimpanzees have been exposed to music from humans, there is no evidence that suggests they can comprehend or enjoy it in the same way that we do.

Chimpanzees do not have the same neural structures as humans that are specialized for music processing, and they lack the vocal apparatus that allows us to produce a wide range of pitches and tones. While they may be able to recognize and differentiate between certain musical patterns and sounds, they do not appear to have the cognitive ability to understand the emotional or cultural significance of music.

Furthermore, the concept of "falling on deaf ears" implies a deliberate choice to ignore or reject something, which is a level of intentionality that is beyond what has been observed in chimpanzees. Their responses to music are likely based on their own innate auditory preferences, rather than any conscious rejection or appreciation.

In conclusion, while chimpanzees may exhibit some basic musical behaviors and responses, it is unlikely that they experience or appreciate music in the same way that humans do. The idea of music "falling on deaf ears" is a human concept that does not accurately reflect the limitations and differences in the musical perception of chimpanzees.
