Musical Acoustics from an Audiological Standpoint: A Refresher, Presented in Partnership with AAMHL

---

1.  Quarter wavelength resonators exist in: Flutes, piccolos, trumpets Trumpets, clarinets, trombones Violins, bass, cello Drums, tympani, cymbals

2.  Half wavelength resonators exist in: Flutes, piccolos, trumpets Trumpets, clarinets, trombones Violins, bass, cello Drums, tympani, cymbals

3.  Non-wavelength resonances exist in: Flutes, piccolos, trumpets Trumpets, clarinets, trombones Violins, bass, cello Drums, tympani, cymbals

4.  A clinical technique to measure the resonant nature of a musical instrument is: Real ear measurement Otoacoustic emission testing Admittance testing Comparison with another known type of resonator

5.  The acoustic transformer effect has the effect of: Enhancing lower frequency sound energy Enhancing higher frequency sound energy Lessening lower frequency sound energy Lessening higher frequency sound energy

6.  Damping is independent of: Frequency Intensity Wavelength resonance character Standing waves

7.  Crest factor is related to: Toothpaste Internal damping Side branch resonators Playing intensity

8.  The acoustic impedance of the acoustic inertance is proportional to frequency means: Lower frequency sounds reflect easier Acoustic impedance is frequency independent Low frequency sounds don’t like small spaces High frequency sounds don’t like small spaces

9.  High frequency sounds reflect because of: The short wavelength “seeing an obstruction” The long wavelength “seeing an obstruction” The low frequency sounds are affected by damping The high frequency sounds are affected by damping

10.  Two examples of the acoustic transformer effect are: Piccolo and flute Trumpet and French horn Drums and string bass Flute and violin
