Final answer:
The statement "Dog trainers can experience hearing loss from using a "silent" dog whistle" is true. Dogs have a wider hearing range than humans, allowing them to detect sounds we cannot. They use the timing difference of sound reception in each ear for pinpointing sound sources.
Step-by-step explanation:
Dog trainers experiencing hearing loss from a "silent" dog whistle is a statement that could be true, but it is not a widely acknowledged issue. A silent dog whistle produces sound at a frequency higher than the human hearing range but within a dog's hearing range.
Therefore, while the sound is imperceptible to most humans if a trainer were to use it excessively at a high volume, they might experience hearing damage over time. Indeed, prolonged exposure to any sound, even those we cannot hear, can potentially cause hearing loss.
As for how dogs hear sounds we cannot, when you grew up with a family pet, you may have noticed they react to noises you don't hear. Dogs have a broader hearing range than humans, which means they can detect higher-frequency sounds that are inaudible to us.
If explaining this to a friend, you would mention that dogs have superior hearing capabilities, characterized by their ability to hear at both higher and lower frequencies than humans can.
The ability of a dog to locate a sound is sophisticated. Dogs use the timing of sound reception in each ear to determine where a sound is coming from, which is a process known as sound localization.
The two ears receive the sound at slightly different times, allowing the dog to use this difference to pinpoint the direction of the sound, much like humans do but with greater sensitivity and over a broader range of frequencies.
Hence, the statement is true.
