R E A L -WOR LD S OLU T IONS TechUpgrade New Sound System Design riginally built in 1893, O Dartmouth College's Memorial Field was constructed as a tribute to the Dartmouth students and alumni who died serving in World War I. In the past year, Acentech Inc. provided sound system design, sound emissions modeling, and regulatory compliance veriﬁcation for the historic stadium. To address the shortcomings of the stadium's outdated sound system, Acentech designed a new sound system that greatly improves speech intelligibility and pattern control of the loudspeakers and provides greater listening coverage for the audience and athletes. The improved sound system is used for live announcements; referees' calls; and playbacks of pre-recorded announcements, music, and marketing messages. Through optimal design and computer modeling, the new system directs sound into the stadium rather than the adjacent neighborhoods, complying with the Town of Hanover's Noise Ordinance. After installation, Acentech measured the resulting sound levels, conﬁrming compliance with the Town's sound level requirements. On another corner of the campus, Acentech provided sound emissions modeling and public address (PA) system design recommendations for the Dartmouth Softball Park, a newly constructed National Collegiate Athletic Association (NCAA) compliant softball ﬁeld that includes a FieldTurf playing surface and seating for 400 fans wrapped around the inﬁeld. The inclusion of a PA system, to provide announcements and play-by-play summaries during games, presented a concern to the surrounding residential neighbors and the Town of Hanover Planning Board. Working closely with Dartmouth College and the PA system designers, Acentech successfully minimized acoustical impacts of the PA system to the community. Acentech Having also collaborated with Dartmouth College on more than 30 projects in the last 10 years, Acentech recently completed consulting work for two projects involving sound systems at the College's Memorial Field and the Dartmouth Softball Park. recommended the design of the system to include numerous noise-reducing features including sound level limiters, selectively aimed loudspeakers, and limitations on the hours of usage of the system, to comply with the Town of Hanover's sound level requirements.
