About Us

Ringrazio was founded by our Managing Director, Sudhanshu Sharma, a 1985 engineering graduate of The Indian Institute of Technology, and a Management Graduate from The Faculty of Management Studies, Delhi University.
Sudhanshu began his career in the world of Airconditioning and Refrigeration in 1987, with Blue Star Limited in New Delhi. He then ventured into the sales and marketing of noise and vibration control products in 1991 in the Middle East.
Equipped with nearly 30 years of experience in the field of acoustics, he established Ringrazio to cater to the Noise Control Industry in the Indian Subcontinent and South Asia.

Ringrazio specializes in designing, supplying and installing acoustical products.
Headquartered in New Delhi, we aim to provide quality and innovative solutions to everything related to noise & vibration control. We develop custom products and provide the optimum solution as per customer’s individual needs and their sound and vibration problems.

The key to our successful problem-solving ability is largely due to a rich interdisciplinary experience – HVAC and Noise and Vibration Control.
