Clarinet Acoustics: Introducing a Compendium of Impedance and Sound Spectra
نویسنده
چکیده
The acoustic behaviour of wind instruments is largely determined by their acoustic impedance spectrum measured at the embouchure or 'input' to the instrument. The acoustic impedance Z is the ratio of acoustic pressure p U and its extrema identify the frequencies of resonances and antiresonances due to standing waves in the bore. (For example see [1].) Backus [2] reports measurements of the acoustic

Saxophone Acoustics: Introducing a Compendium of Impedance and Sound Spectra
We introduce a web-based database that gives details of the acoustics of soprano and tenor saxophones for all standard fingerings and some others. It has impedance spectra measured at the mouthpiece and sound files for each standard fingering. We use these experimental impedance spectra to explain some features of saxophone acoustics, including the linear effects of the bell, mouthpiece, reed, ...
متن کاملThe Acoustic Impedance of Bb Clarinet
To better understand the unique tone of both a plastic and wooden clarinet, an analysis of sound production was taken by several methods. The sound output from the clarinet was recorded and run through a phase-sensitive wave analysis program to determine the phase relations, frequencies, and intensities of the most prominent harmonics. Using a piezoelectric transducer, phase-sensitive measureme...
متن کاملHow to play the first bar of Rhapsody in Blue
To play the glissando opening Gershwin’s Rhapsody in Blue, expert clarinettists combine unusual fingerings with even more unusual vocal tract configurations to achieve a nearly continuous rise in pitch. To study directly the player’s vocal tract when performing the glissando, we incorporated an acoustic impedance measurement head within a clarinet mouthpiece. The player’s vocal tract impedance ...

Introduction: In Iran country, there is a lack of reliable data on acoustic characteristics of building materials applied in the offices and industrial rooms. This study aimed to investigate noise absorption characteristics for current building and acoustics materials and provided the acoustic database. Method: In this cross sectional study, the minimum of 60 building and acoustic mate...
متن کاملPitch bending and glissandi on the clarinet: roles of the vocal tract and partial tone hole closure.
Clarinettists combine non-standard fingerings with particular vocal tract configurations to achieve pitch bending, i.e., sounding pitches that can deviate substantially from those of standard fingerings. Impedance spectra were measured in the mouth of expert clarinettists while they played normally and during pitch bending, using a measurement head incorporated within a functioning clarinet mou...
