Problem: Gramophone record:

A further limitation of the gramophone record is that fidelity steadily declines as playback progresses; there is more vinyl per second available for fine reproduction of high frequencies at the large-diameter beginning of the groove than exist at the smaller-diameters close to the end of the side. At the start of a groove on an LP there are 510 mm of vinyl per second traveling past the stylus while the ending of the groove gives 200210 mm of vinyl per second less than half the linear resolution. Distortion towards the end of the side is likely to become more apparent as record wear increases.*

What is a drawback of using gramophones?

Problem: Gramophone record:

Some recordings, such as books for the blind, were pressed at 16 23 rpm. Prestige Records released jazz records in this format in the late 1950s; for example, two of their Miles Davis albums were paired together in this format. Peter Goldmark, the man who developed the 33 13 rpm record, developed the Highway Hi-Fi 16 23 rpm record to be played in Chrysler automobiles, but poor performance of the system and weak implementation by Chrysler and Columbia led to the demise of the 16 23 rpm records. Subsequently, the 16 23 rpm speed was used for narrated publications for the blind and visually impaired, and were never widely commercially available, although it was common to see new turntable models with a 16 rpm speed setting produced as late as the 1970s.

What was 16 2/3 rpm speed used for?
---
A: narrated publications
