t;rnllouin shifts and the line widths in NII4HS04 which eoncerrt the longitudinal.t=tonons rrorazatinx along the a', b and c directions were measured in the term-.erature ranue - 115--3O'C. l"he Brillouin shift caused bv the pUIC lonuitudinalacoustic rhonons r>rot>auatinx alona the b axis shows an abrur>i decrease and theline width increases below the ur>r>or r>araelectric-ferroelectric transition tentpera-ture. the czuasi-Ionxil:tmdinal comr>onent along the a' axis shows a small anomalvj. the shift near the transition temperature. No unambisuous anomalies wererouna irt the shift and the line width of the czuasi-lonaitudinal comr>onent alonxthe c axis.
