Whistling sound

when driving at low speed, I hear a low pitched whistle like sound. It is particularly audible when slowing down to a stop, and starting up again. If I were to guess where it is coming from, it sounds like it may be localized to the right front wheel. Any clue what this could be?

Vehicle year, make, and model, please?

Are there any other symptoms accompanying the noise?
