272:, renowned UCLA acoustical physicist, "The distribution of the low frequency normal mode in a rectangular room", which was considered later as the benchmark for applied normal mode theory and room acoustics. At Harvard, he involved in the research task of "The decay of sound in rectangular room" and published a series of papers on the topic. In his lifetime, Ma published some 30 papers on room acoustics based on normal mode theory, and around 150 including other topics, thereafter. Ma published more than 180 papers on room acoustics and some other subjects. 322:(1966-1976), Ma was under house arrest. But according to a paper published the same year by one of his post-graduate student, Tian Jing (田静), in 1966, Ma gave a formula of jet noise power via air pressure and invented micro-perforated panel absorbers and micro-perforation jet mufflers. These were the main missions of a ad hoc task force Ma headed, in order to prepare for the missile tests China was about to launch. 299:
In 1956, Ma designed and built the first acoustics laboratories in China, including reverberation chambers, sound insulation measurement rooms, anechoic chamber, high intensity acoustic noise testing chamber, and water tank for
