In this Section, a few examples of piano tones are presented. For each piano, the sound is recorded by a single microphone located at a vertical distance of one meter from the soundboard, above the attachment point of the strings C4.
JB36_Pressure_Treble.mp4This recording contains the sound pressure radiated by the J.B. Streicher 1836 piano, for the six notes played from B6 to F#6, in descending order. The aural comparison with the recordings of the soundboard acceleration for the same notes, presented in Section 2.C., suggests that, in this treble range, the sound of the instrument is composed of other contributions than the only soundboard. Do you agree?
JBS51_Pressure_notes_D#1_C2.mp4This example includes the sound recording of the notes D#1 and C2 played on a piano J.B. Streicher 1851. These sounds show a rather close similarity with the corresponding soundboard accelerations presented in Section 2.C, although they contain less energy in the high frequency range.
