It needs adjusting
Is it a "whistling" or a high pitched squeeling sound? If squeeling, it could be the signal that the front brake pads are in need of replacement.
With a low-pitched sound, the eardrum moves more slowly with gentle vibrations. The larger surface area of the eardrum allows it to capture more of the low-frequency waves and transmit them to the inner ear for processing.
Loudness is the same thing as volume. It refers to the amplitude of a sound wave. Pitch is the quality of a sound where it sounds "high" or "low", as a "high-pitched squeal" or a "low-pitched rumble". It refers to the frequency of the sound wave. Intensity refers to the power of a wave.
I was mystified by this high pitched squeel - so were many dealers...

To effectively scare dogs away using a whistle, blow the whistle loudly and sharply when the dog approaches. The high-pitched sound is unpleasant to dogs and can startle them, causing them to retreat. Repeat as needed until the dog leaves the area.
Ultrasonic sound technology can deter mice by emitting high-frequency sound waves that are unpleasant for them, causing discomfort and driving them away from the area.
To effectively scare dogs away using a dog whistle, blow the whistle at a high frequency that is uncomfortable for dogs to hear. This high-pitched sound can startle and deter dogs from approaching or staying in the area.
