Company Profile
CSTI performed its first job in acoustics in 1987. Today, we still collaborate with our clients to efficiently solve acoustical problems. We enjoy the challenge of finding solutions for air-borne noise, structure-borne noise, vibration of equipment and structures, acoustic induced vibration, hearing loss, detectability of sounds, literature searches, and product noise/vibration. We put forth our best efforts to solve these problems for clients.
