| absorción acústica | acoustic absorption |
| aislamiento acústico | acoustic insulation The process of preventing the transmission of sound by surrounding with a nonconducting material |
| aparato de señal acústica | alarm signal |
| barreras acústicas | noise barrier |
| barreras acústicas | noise barrier Barriers for reducing the propagation of sound: they are widely used in industry and alongside roads and railways to shield receivers from noise sources. Barriers will not reduce the noise on the receivers side, but will increase it, unless the barrier is also covered in absorbing material |
| calidad acústica | acoustical quality |
| calidad acústica | acoustical quality The characteristics of a confined space that determines its ability to enable music and speech to be heard clearly within it |
| certificado de acústica de una aeronave | noise certification of an aircraft |
| confort acústico | acoustic comfort |
| contaminación acústica | noise disamenity |
| contaminación acústica | noise pollution of the environment |
| contaminación acústica | noise pollution Harmful or unwanted sounds in the environment, which in specific locals, can be measured and averaged over a period of time |
| contaminantes acústicos | noise pollutant |
| contaminantes acústicos | noise pollutant Noise in the environment which can be harmful to human beings, animals and plants |
| estallido acústico | sonic boom |
| estallido acústico | sonic boom A noise caused by a shock wave that emanates from an aircraft or other object traveling at or above sonic velocity |
| filtro acústico | acoustic filter A device employed to reject sound in a particular range of frequencies while passing sound in another range of frequencies |
| material para aislamiento acústico | sound insulation material |
| material para aislamiento acústico | sound insulation material Material used to reduce the transmission of sound to or from a body, device, room, etc. |
| nivel acústico | acoustic level |
| nivel acústico | acoustic level Physical quantity of sound measured, usually expressed in decibels |
| nivel de emisión acústica | noise emitted |
| perfil acústico | acoustic profile |
| planificación acústica | acoustical planning |
| propiedad acústica | acoustic property |
| propiedad acústica | acoustic property The characteristics found within a structure that determine the quality of sound in its relevance to hearing |
| propiedades acústicas | acoustic property |
| riesgo acústico debido al ruido de los juguetes | risk of damage to hearing resulting from noise emitted by toys |
| sistema acústico | hearing system |
| sistema acústico | hearing system The system that is concerned with the perception of sound, is mediated through the organ of Corti of the ear in mammals or through corresponding sensory receptors of the lagena in lower vertebrates, is normally sensitive in man to sound vibrations between 16 and 27.000 cycles per second but most receptive to those between 2.000 and 5.000 cycles per second, is conducted centrally by the cochlear branch of the auditory nerve, and is coordinated especially in the medial geniculate body |
| zona de medida acústica | sonic sensing zone |
| zonificación acústica | acoustic zoning |
