从声学的角度来解释,哨子这种乐器的基本发音结构是由声源体（哨子吹口后部的发音棱部分 ）和共振体（哨子共鸣腔内的空气）两部分组成,它们分别具有能源接纳、声源形成、共振和声波扩散等功能.哨子的发音是以人体肺部呼出的气流为动力的,在演奏时,气流通过双唇控制风口,形成一束与吹孔的发音棱相对应的气流,在适当的距离,以准确的角度和相应的流速吹至吹孔的发音棱,从而引起边棱振动并产生边棱音,同时也激发了哨子共鸣腔内空气的共振,形成驻波而发音 （驻波是一种特殊的波干扰现象,它是由振幅相同,频率相同,振动方向相同而传播方向相反的两列波迭加而成的合成波）.这种以空气振动而发音的乐器,按乐器声学分类法（即霍恩博斯特和萨克斯的乐器分类体系——H——S系统）属于气鸣乐器.在此类乐器中,由于声源体的结构不同,因此产生了不同的振动方式,其中,以边棱作为声源体并引发管身内空气柱共振的振动方式,称为边棱音振动 （也称边棱振动）.以边棱音振动而发音的气鸣乐器,被称为边棱乐器,哨子这种乐器就是边棱乐器,它有属于其自身的发音原理、发音规律和共振特点.由于哨子这种乐器的基本发音结构是由声源体和共振体两部分组成,因此,下面分两部分来具体解释长笛的发音原理：声源——哨子的边棱音振动；共振——共鸣腔的空气振动.

Explained from the point of view of acoustics, whistle basic pronunciation structure of this instrument is made up of the sound source body (whistle blowing the pronunciation part) at the back of the mouth and the resonance body (air whistle resonance cavity) in two parts, respectively formed with acceptance, energy source, resonance and sound wave spread, etc. Exhaled air whistle sounds in a person's lungs for power, when playing, airflow through the lips control tuyere, forming a beam and the pronunciation of blow hole edge corresponding to the air, at the right distance, accurate Angle and the corresponding flow velocity blow to the pronunciation of blow hole edge, causing vibration and produce edge, edge also inspired air whistle resonance cavity resonance, the formation of standing wave and pronunciation (standing wave is a special kind of wave interference phenomenon, it is by the same amplitude, frequency, same same direction of vibration and transmission in the opposite direction the synthesis of the two columns of wave superposition of wave). In the air the vibration and sound instruments, according to the instrument acoustic classification (namely HuoEnBo and Isaac
