eli5: Why do old recordings (tv / audio) sound so nasally?

1.10K views

Watching old movies or broadcasts always sound the same. Everyone has a very muffled and nasal sound to them. What caused microphones to produce such a uniformly weird sound?

Don’t forget there’s another reason. Reproduction at the time came via CRT TVs which rather than the modern integrated soundbars or high end 5.1 systems, actually came with weedy singular paper cones. These cones had poor slow response times, were tiny and generally incapable of producing low frequencies. As such, replaying a varied high-range soundtrack would be unlistenable on a period TV.

To combat this, low frequencies were reduced and engineers tried to funnel sound through the frequencies that CRT speakers could produce clearly. With the advent of decent reproduction, these now sound hideous and date recordings badly.
