adjective. The definition of acoustic is music that is played without the use of electronic amplification equipment. An example of the word acoustic is a song in which only a flute is used. Acoustic is defined as the sense of hearing. An example of the word acoustic is to refer to your ability to hear sound. acoustic. Acoustic means having to do with sound. If you prefer the softer sound of acoustic rock, it means you like rock played on acoustic instruments. These include the guitar, violin, 'cello, viola, or harp––anything really that does not rely on electrical amplification to be heard. acoustic Sentence Examples Its acoustic properties are said to be almost perfect, and it has been named "the Auditorium. " The acoustic properties of the theatre are extraordinarily good, a speaker in the orchestra being heard throughout the auditorium without raising his voice. Acoustic energy can be defined as the disturbance of energy which passes through matter in the form of a wave. In other words, it is the energy concerning the mechanical vibrations from its components is called Acoustic Energy. adjective Also a·cous·ti·cal. of, relating to, or being a musical instrument whose sound is not electrically enhanced or modified.
noun. the sensation produced by stimulation of the organs of hearing by vibrations transmitted through the air or other medium.
An acoustic guitar is a musical instrument in the guitar family, that projects the sounds of its vibrating strings acoustically through the air. Originally just called a guitar, the retronym 'acoustic guitar' came in use to distinguish it from an electric guitar, that relies on an electronic amplification system.
Medical Definition of Acoustic Acoustic: Having to do with sound or hearing. The acoustic nerve (the 8th cranial nerve) is concerned with hearing and the sense of balance and head position. An acoustic neuroma is a benign tumor on the acoustic nerve.
How to Play Guitar Chords Place your index finger on the third string at the second fret, your middle finger on the first string at the second fret, and your ring finger on the second string at the third fret. Leave the fourth string open. Strum the bottom four strings. Pay attention to the sound. That's the D-chord!
An acoustic guitar is a fretted musical instrument that produces sound via vibrating strings above a hollow chamber in the guitar's body. The vibrations carry through the air and do not require electrical amplification (although many acoustic guitars also function as electric guitars).
noun, plural sta·di·ums, sta·di·a [stey-dee-uh]. a sports arena, usually oval or horseshoe-shaped, with tiers of seats for spectators. an ancient Greek course for foot races, typically semicircular, with tiers of seats for spectators.

Knowledge in acoustics is essential to promote the creation of environments, both indoors and outdoors, involving rooms with good listening conditions for speakers, musicians and listeners and also living environments and working areas which are reasonably free from harmful and/or intruding noise and vibrations and
Sound energy travels in waves and is measured in frequency and amplitude. The energy in a sound wave can be measured using Decibels. The Decibel Meter shows examples of things that make noise and measurements in decibels. Amplitude measures how forceful the wave is.
Acoustical materials are a variety of foams, fabrics, metals, etc. Sound and noise are managed by four methods: blocking, absorbing, diffusing, and isolating. Blocking relates to the use of soundproofing. Absorption works by converting sound energy into heat. Diffusion seeks to scatter sound without deadening a room.
Acoustical properties are those that govern how materials respond to sound waves, which are what we perceive as sound. Just as with waves on the surface of water, these air waves are peaks and valleys of relatively high and low pressure that can be sensed as oscillations of air pressure at a given frequency.
The loudness of sound is measured in units called decibels (dB). A decibel unit expresses the relative intensity of sounds on a scale from zero for the average least perceptible sound to about 100 dB, which is near the level most people find uncomfortably loud.
