本申请公开了一种啸叫检测方法、装置及电子设备，该方法包括：电子设备获取了以功率谱峰值所在频点为中心的第一频点集合和第二频点集合，并根据第一频点集合中的两两频点之间的第一功率比确定第一参考频点，以及根据第二频点集合中的两两频点之间的第二功率比确定第二参考频点，从而可以根据第一参考频点与第二参考频点之间的频点数量确定功率谱峰值所在频点存在单音或者啸叫。该方法可以区分存在单音的频点和存在啸叫的频点，提升啸叫检测的准确性。 The invention discloses a howling detection method and device and electronic equipment, and the method comprises the steps that the electronic equipment obtains a first frequency point set and a second frequency point set which take a frequency point where a power spectrum peak value is located as a center, and determines a first reference frequency point according to a first power ratio between every two frequency points in the first frequency point set, and a second reference frequency point is determined according to a second power ratio between every two frequency points in the second frequency point set, thereby determining that the frequency point where the power spectrum peak value is located has a single tone or howling according to the number of the frequency points between the first reference
