For example, when lifting or lowering a precision machine using a crane, winch, etc., it is necessary to do so at extremely low speeds to prevent shocks, and in this case, the hydraulic actuator is operated at extremely low speeds, so only one mode can be set. If the proportional constant of the frequency to the operating speed is constant, the intervals between the intermittent sounds will be either too long or too short, making it difficult to accurately recognize the operating speed of the hydraulic actuator. In particular, when the interval between intermittent sounds is too long, the silence between the preceding and succeeding sounds becomes longer and the sound is aurally elongated, making it difficult to hear.

On the other hand, if the proportional constant of the frequency with respect to the operating speed can be changed, it is possible to set the proportional constant according to the operating speed and make the interval between the intermittent sounds easier to hear.
