Reverberation - Study guides, Revision notes & Summaries

Diffraction The bending of a wave as it moves around an obstacle or passes through a narrow opening Refraction The bending of a wave as it passes at an angle from one medium to another Reverberation collection of reflected sounds in an enclosure, such as room. Early reverberation (good) the sound that reaches the listener after a small number of reflections. Enhances comprehension when listening with two ears. Late reverberation (bad) the sound reaching the listener after several reflections...

db loss of a perforation of TM : 10-15db loss procedure done to fix perforation : tympanoplasty or myringoplasty monomeric spots : looks like a hole in TM, but reflects light like a mirror. holes that have healed. aka "mirror membranes" average dimentions of an adult eardrum : 2.3-2.9cm in length, .7cm in diameters pars tensa : lower 4/5 of TM and tight pars flaccida : upper 1/5 of TM and flaccid 2 | P a g e otis externa : "swimmers ear" - inflammation of the walls of the EAM...

CTD 250 Final Exam Questions & Answers 2024-25 Reflection - ANSWERSThe portion of the sound not absorbed when striking a surface is called a Hz - ANSWERSThe number of wavelength cycles completed per second is measured as True - ANSWERSIn order to achieve better speech privacy, it is sometimes necessary to increase reverberation. True - ANSWERSPoor IAQ, improperly designed HVAC, and VOCs can contribute to SBS and BRI. False - ANSWERSSound waves travel through water faster than wo...

When localizing a sound (determining the direction the sound is coming from), our two ears use THREE mechanisms to localize the sound source. Correct Answer-Arrival time, Intensity, and Pinnae Reflection Direct sound... Correct Answer-tells us the location, size, and timbre of the source The best way to listen to a binaural head recording is by Correct Answer-sitting directly between 2 loudspeakers. "Direct Sound", "Early Reflections", and "Reverberation" make up what we call the ...

Color Doppler demonstrates (x2) - average velocity & direction of flow Which artifacts will be seen with needles? (x3) - - Propagation speed artifact - Reverberation AKA resonance artifact - Bayonet artifact What happens if you decrease the color threshold? - reduce the color displayed - color threshold AKA priority - increase threshold if you don't see enough color If the entire image is too bright, what do you do first? - decrease the output power reverberation artifact due to gas pro...
