![]() ![]() Also the amount of acoustical absorption required to reduce reverberation and noise.ĪCOUSTICAL CONSULTANT: A professional usually with an engineering degree who is experienced in providing advice on acoustical requirements, and noise control in a variety of situations.ĪCOUSTICAL ENVIRONMENT: The acoustical characteristics of a space or room influenced by the amount of acoustical absorption, or lack of it in the space.ĪCOUSTIC IMPEDANCE: Also known as the acoustic ohm, impedance is the resistance to the flow of sound through a medium. The two most common accelerometer types are the traditional charge type and the integrated electronic piezoelectric type.ĪCOUSTICAL SOCIETY OF AMERICA (ASA) : An organization that publishes standards and information related to the study and applications of acoustics.ĪCOUSTICAL: The properties of a material to absorb or reflect Sound (adjective) Acoustically, (Adverb).ĪCOUSTIC CALIBRATOR: An instrument providing a reference noise source used to calibrate the performance of sound level meters.ĪCOUSTICAL ANALYSIS: A review of a space to determine the level of reverberation or reflected sound in the space (in seconds) influenced by the building materials used to construct the space. The term is derived from the Greek word akoustos, meaning “heard.”ĪCCELEROMETER : A vibration sensor and transducer that contains an electrical output that is directly proportional to the acceleration component of the vibration. The branch of physics that treats the phenomena and laws of sounds as it affects people. Acoustics is concerned with the production, transmission, control, and effects of sound and studies mechanical waves, like vibration and ultrasound. Please reference the glossary terms below for the many different words and terms typically found in acoustics.ĪCOUSTICS: The science of Sound. Every single object has a unique natural frequency of vibration and the degree to which sound is transferred between two materials depends on how well their acoustical impedances match.Īudio terminology are common phrases found in the science of sound, acoustics. These sound frequencies efficiently induce vibration in the tympanic membrane of the ear. Sound waves are pressure waves that travel throughout the Earth’s atmosphere. It is hoped that the plain language approach will provide a better understanding of the sound terminology frequently used in the field and set you up for success!įAQ What is meant by the transmission of sound? This glossary of acoustical definitions and sound terms has everything you need to dive deep into the world of sound and acoustics. A good place to start is learning the different terms. Learning about acoustics, the science of sound, can be challenging when there are so many unique and difficult terminologies.
