To understand speech and music and the principle of the auditory system, we must return to those primitive aspects of music and speech production in nature to determine and isolate mechanical features that underlie each auditory sensation. Any other procedure, by the terms of the body-image theory of sound, is an illusion. They have not worked, they do not work, and will never work.
A very weak conclusion, not at all supported by evidence in the paper which is mainly just a bunch of ramblings to support statements/conclusions attributed in general and specifically that are not even factual. I am guessing they were desperate for papers for the 2nd International Conference on Acoustics in Nigeria. Beautiful country, nice people, not well known for academic regour (note author is listed as independent researcher and no indication of peer review, which, is not uncommon at these conferences.)
I must admire his conclusion which does not even recognize that he could be wrong, which, without establishing any evolutionary influence for music negates his conclusion. Frankly, the whole work basically implies that everyone has a super simplistic view when pretty obviously we understand there are complex mechanisms right from physical detection up to interpretation. The whole thing is a mess. I am with Mapman, I am sorry I wasted any time reading it.
