Acoustic rhinometry is a diagnostic measurement of cross sectional area and length of the nose and the nasal cavity through acoustic reflections. [1] It can be used to measure nasal anatomical landmarks, and nasal airway changes in response to allergen provocation tests.
Here, examples include tweaking an automobile door latching mechanism to impress a consumer with a satisfying click or modifying an exhaust manifold to change the tone of an engine's rumble. Aircraft designers are also using acoustic instrumentation to reduce the noise generated on takeoff and landing.
If there is no significant improvement after decongestant, anatomical abnormality, like deformity of cartilage or bone within nasal cavity is suspected. However, such measurements allow only to detect in which side of the nose there is obstruction, not the location within the nasal cavity, which can be detected by acoustic rhinometry or ...
Acoustic rheometer measures sound speed and attenuation of ultrasound for a set of frequencies in the megahertz range. These measurable parameters can be converted into real and imaginary components of longitudinal modulus. Sound speed determines M', which is a measure of system elasticity. It can be converted into fluid compressibility.
A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out. A tuning fork's ...
Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [1] [2] [3] psychophysics, [4] organology [5] (classification of the instruments), physiology, [6] music theory, [7] ethnomusicology, [8] signal processing and instrument building, [9] among other disciplines.
Radar wind profiler and RASS at the Alaska North Slope site in Barrow, Alaska. A radio acoustic sounding system (RASS) is a system for measuring the atmospheric lapse rate using backscattering of radio waves from an acoustic wave front to measure the speed of sound at various heights above the ground.
Archaeoacoustics is a sub-field of archaeology and acoustics which studies the relationship between people and sound throughout history.It is an interdisciplinary field with methodological contributions from acoustics, archaeology, and computer simulation, and is broadly related to topics within cultural anthropology such as experimental archaeology and ethnomusicology.
