BBN became bigger during the 1950s. The partnership moved from the rented rooms at MIT to another office and eventually occupied a three storey building in Cambridge. Because of the rapid growth of the partnership, BBN was incorporated in 1953. Beranek resigned from MIT and served as Chairman and CEO of the company. During this period, the company set up five research divisions including acoustics, life and information sciences, noise control and applied physics. Some of their significant discoveries include the voice masking for privacy, muffling system for Boeing aircraft which reduced the noise cause by the propeller by 15 decibels, structural dumping and the development of the Artificial Intelligence (AI) program for pattern recognition. The company purchased its first computer (LPG-30) from Royal McBee company in 1958.<ref>[http://www.bbn.com/about/timeline/ Timeline- 1950s]</ref> <ref>[http://mit.edu/6.933/www/Fall2001/BBN.pdf Section 2: 1948-1957:The Early Years of BBN]</ref>
