Scientists have tested an ear cap fitted with special earphones that play music into the horse's ears.
Researchers believe that playing classical music directly into horses' ears reduces their anxiety even further. They say country music can calm horses down, while rock and jazz have the opposite effect.
Meanwhile, scholars also found that the horses recovered from stress more quickly if they had classical music played into their ears.
The horses heart rate also slowed down more quickly when the animals had classical music playing into their ears. The horse headphones cost 850 dollars and can be bought online.
