For more than 45 years since its establishment, OTO has supported customers in acoustic planning, sound and vibration countermeasures as a group of specialists in all fields related to "sound and vibration".

In particular, our company continues to focus on providing engineering capabilities that we are not ashamed of as a group of specialists.

More than 60% of our engineers are certified environmental metrologists, and all are working toward becoming certified. Each of our engineers, who are well versed in their respective fields, is involved in projects in every direction, creating a system that allows us to effectively demonstrate the collective strength of our group of specialists. Thanks to this, we have received numerous requests over the years from many of our clients, and the number of requests we handle each year has reached over 700.

We always ask our clients about their objectives and subsequent plans, no matter what the request is, in order to set them on a path to effectively achieve their goals. We not only conduct the requested research and measurements, but also provide expert advice to help our clients develop appropriate measures and stories to address their issues and concerns.

We hope that our customers will continue to make use of us as a partner in "sound and vibration", not only for survey measurements, but also for proposing countermeasures and consulting based on the results.
