Inventor's Remarkable Results in Dealing With Sound Stockholm, Mar, 15.
Professor H. Kreuger, of the Royal College of Technology of Stockholm, has reached a series of remarkable results in mastering the elusive sound waves and has. also been able to remodel and to improve the acoustics of large concert and assembly hally in Sweden by his new methods, In order to define the sound isolating, qualities of different building constructions, the professor hax invented new devices, capable of measuring the volume and strength of the sound within wide limits, from very strong sound down to those that are hardly audible to the physical car. By means of these Instruments, it has been possible to photograph the sound waves, to define their special characteristics and to investigate the transmission of the sound through walls, doors, windows, pipes, ete.
Hand in hand with this work he Tas specialized in a different field, the investigating and improving: of acoustics in large rooms and halls. Thus, the neoustics of the new con-cart hall In Stockholm. originally. turned out to be a considerable disappointment, but Professor Krewger, through certain comparatively 8 changes in the structure of the hall, was able to eliminate the drawbnel and to make the acoustics satis factory. Similarly excellent results have been reached in other well. known assembly halls in Stockhol and: Gothenburg. Through this work "the elusive problem acoustics seems to have been sold in so far ax good acoustics can be secured without fail in both old and new buildings—Reuter,
