TNO is an independent research organisation established by law as legal public entity, resulting in certain societal responsibilities to create solutions to the challenges that society presents us. AS one of its core themes, TNO aims for achieving a sustainable society. To achieve this, we at TNO focus on a sustainable living environment, sustainable energy, and a sustainable industry. We’re looking for integrated solutions at the system level. These are solutions that balance the changing needs of society, the environment, and the economy. TNO’s acoustics and sonar group strives to support governments and industry in the Netherlands and abroad to better understand, use and control sound. Capabilities include model development (numerical and theoretical), experimental testing and monitoring, system and software development, product innovation, and impact and policy studies. Through involvement in European research, standardization work and links with universities and partners, a broad range of acoustic expertise is available.
