1. Adjust the * * vibration frequency: By punching holes in the eardrum, the * * vibration frequency and resonance mode can be changed to adapt to different music styles and performance requirements. The position and size of the hole will affect the vibration frequency of the eardrum, thus adjusting the pitch and timbre of the drum sound.
2. Control the volume and attenuation: Punching can effectively reduce the volume of drum sound and attenuate the long vibration time. This is very useful for performance environments that need to control the volume, such as performing in a recording studio or a small place.
3. Adjust the sound quality: Punching can also change the peak value and frequency response characteristics of the eardrum, thus affecting the sound quality of drum sound. Different sizes and shapes of holes will have different effects on sound quality, such as increasing the uplink frequency and lowering the bass. Generally speaking, the purpose of drilling holes is to make the sound of trumpet drums more flexible and adjustable to meet different performance needs and personal preferences. According to different musical styles, playing skills and personal preferences, holes in different positions and numbers can be punched in the eardrum to achieve the required acoustic effect.
