The Acoustics and Vibration Group at ICAT-UNAM was founded in 1981. It has a national leading  role and international recognition for its research and technical work in the areas of acoustic instrumentation, acoustic measurements, acoustic signal processing, nonlinear acoustics, and musical acoustics. The group collaborates at UNAM with the faculties of Sciences, Engineering, Architecture, Psychology, Medicine, and Music, as well as with the scientific and technological research institutes of Physics, Engineering, and Astronomy. International collaborations include: Universidad Politécnica de Valencia (Spain), Universidad de Sevilla (Spain), Université du Maine (Le Mans, France), Baldwin-Wallace University (Ohio, USA), University of Edinburgh (Scotland, UK). Members of the group teach and supervise student projects at UNAM’s graduate programs in Physical Sciences, Engineering, and Music, with additional participation in the programs of Architecture, Psychology, and Medicine. Other national academic and educational institutions seek advice from members of the group and participate in guided visits to the Acoustics Laboratory. The group also collaborates with local and federal government agencies such as CENAM (Centro Nacional de Metrología, National Center of Metrology), SEMARNAT (Secretaría de Medio Ambiente y Recursos Naturales, the Mexican agency for the environment and natural resources), PAOT-CDMX (Procuraduría  Ambiental y de Ordenamiento Territorial de la Ciudad de México, the agency for environmental land use planning of Mexico City), on issues regarding acoustic measurements, urban and environmental noise, acoustic conditioning, and others. The group also offers consultancy and measurement services for industrial clients conducting measurements of acoustic characteristics of materials and acoustic elements, measurement and control of noise and vibration, acoustic conditioning, among others.
