Pan Flute (Music in the Air)
★Exhibit Content: Interactive acoustic science popularization model experience of sound resonance and pitch variation of vibrating air columns ★Interaction: Approach the tube openings to listen, and compare the resonance sounds of different air columns through model interaction ★Operation: 1. Bring your ear close to the opening of each sound tube and listen carefully to the sound coming from inside. 2. Approach tubes of different lengths one by one to listen, compare the pitch differences of the sounds produced by each tube, and look for the pattern of sound variation. ★Exhibit Description: The "Pan Flute" is a tabletop science popularization exhibit on the theme of acoustic resonance, belonging to the acoustics science popularization area and recommended by the KexMall exhibit store. The exhibit uses a white and blue square sheet metal tabletop cabinet, with a stainless steel inclined bracket mounted on the tabletop, on which 7 colored sound tubes of uniform diameter and different length gradients are fixed. The enclosed air column inside the tubes can resonate with ambient sound waves. Visitors approaching the tube openings can hear resonance sounds of different pitches, intuitively demonstrating the correspondence between air column length, vibration frequency, and pitch, simulating the sound production principle of the traditional pan flute instrument. ★Scientific Principle: 1. An enclosed air column forms inside the tube. The air column has a natural vibration frequency. External ambient sound waves excite the air column to vibrate, producing resonance and amplifying the sound. 2. The length of the sound tube determines the length of the air column. The longer the air column, the lower the natural vibration frequency and the lower the pitch; the shorter the air column, the higher the vibration frequency and the higher the pitch. The 7 sound tubes of different lengths correspond to 7 resonance sounds of different frequencies, intuitively presenting the pattern of pitch variation.

★Exhibit Content: Interactive acoustic science popularization model experience of air column resonance, pitch and tube length ★Interaction: Approach the tube openings to listen, and compare the resonance sounds of different air columns through model interaction ★Operation: 1. Bring your ear close to the opening of each sound tube and listen carefully to the sound coming from inside. 2. Approach tubes of different heights one by one to listen, compare the pitch differences of the sounds produced by each tube, and look for the pattern of sound variation. ★Exhibit Description: The "Pan Flute" is a ring-shaped floor-standing science popularization exhibit on the theme of acoustic resonance, also known as "Music in the Air", belonging to the acoustics science popularization area and recommended by the KexMall exhibit store. The exhibit uses a circular frame enclosed by a double-layer white metal guardrail, with 7 colored sound tubes of uniform diameter and different lengths vertically installed on the frame. Each sound tube is equipped with a circular base of the same color at the bottom, along with an independent science popularization instruction sign. Relying on the resonance between the enclosed air column inside the tubes and ambient sound waves, sound tubes of different lengths form air columns with different natural frequencies. Visitors approaching the tube openings can hear resonance sounds of different pitches, intuitively demonstrating the correspondence between air column length and pitch, and explaining the sound production principle of traditional wind instruments such as the pan flute. ★Scientific Principle: 1. An air column exists inside the tube. The air column has a fixed natural vibration frequency. External ambient sound waves excite the air column to vibrate, producing resonance and amplifying the sound. 2. The length of the sound tube determines the length of the air column. The longer the air column, the lower the natural vibration frequency and the lower the pitch; the shorter the air column, the higher the vibration frequency and the higher the pitch. The 7 sound tubes of different lengths correspond to 7 resonance sounds of different frequencies, simulating the sound production mechanism of the traditional pan flute.
