The halls of Kensington Palace are about to be filled with noise! Prince George has a new whistle.

Prince William and Kate Middleton were given brass whistles to take home from their trip to a whistle factory on Wednesday — prompting William to say: "Don't show that to George — we'll never get any peace!"

William made the quip as he and Kate were presented with their personalized gifts — an engraved Air Ministry whistle and a rose gold whistle on a necklace — as well as a selection of musical whistles for George, 4, and Princess Charlotte, 2.

The gift came during the couple's tour of Acme Whistles — the creator of the first-ever police whistle — at the end of a busy day of engagements in Birmingham.

Kate was handed a bag containing an assortment of presents for their children, including two brass Samba whistles, a plastic slide whistle and a wooden duck call.

While the Samba whistles are used to play tunes at the carnivals in Rio and in Notting Hill, the slide whistle is best known in Britain for creating the sound of kids' TV show The Clangers.

The 147-year-old, family-owned business still makes its products by hand, including sports whistles used in football and ice hockey. The couple was also given a tour to see the production process, including plating, moulding and welding. They also unveiled a plaque to commemorate their visit.

And the royal parents, who also have a cocker spaniel named Lupo, were shown dog whistles, which can't be heard by humans.

Kate asked, "There are different pitches for different dogs, aren't there?"

Chief Executive Simon Topman, who runs the business with his wife Debbie, told the couple, "Yes, your grandmother would use something that is great for her labradors and retrievers but wouldn't be for your spaniel."

Silversmith Ray Stone, who plates and polishes commemorative items, including a £5 coin made by Royal Mint to mark Queen Elizabeth and Prince Philip‘s platinum wedding anniversary, told William and Kate that the royal family has kept him in a job for years.

"So I'd like to thank the royal family," he said.

"We aim to please, Ray," William joked.
