Very good. In fact it is so good that a horse can hear somone calling it's name from a half a mile away! It can hear a soft whisper that if you told it to trot in a whisper it would trot. I hope my answer helps.
Like all animals (including you), your horse has binaural hearing, meaning his ears can hear sound concurrently. His external ears, known as pinnae, act like satellite dishes to capture sound waves and funnel them to his inner ears. Because of the large, cuplike shape of his pinnae, especially when compared to your small, flat ones, very little sound spills out of them, so he can capture noises you might miss.
Another reason your horse can detect sounds you can't is his ability to hear a wider range of high-frequency tones, such as the ultrasonic squeak of a bat. For a prey animal, which he is, this hearing acuity makes sense. In his natural environment (open plains), other animals, including predators, are the only things besides weather that generate noise. Predators generally don't vocalize when stalking prey, so your horse is hard-wired to listen for the sounds of stealth-the snap, crackle and pop of grass and twigs under, say, a mountain lion's paws.
These telltale rustlings contain high-frequency sounds, which your horse uses to locate the direction from which they came by gauging which ear hears them first and at what intensity. Unlike animals that can hone in on a precise location, your horse needs only an approximate indication of where the sound erupted, so he can prepare to run in another direction. If the sound tells him action may be warranted, he'll follow with eye movement, then finally raise and turn his head so he can better focus, freezing his body so as not to give away his position. (You've probably seen grazing horses do this. You'll notice they also quit chewing, the better to hear.) If he perceives danger, he'll likely spook and run.
A horse can hear from 0-200 decibels, but only to 0-80 without causing the horse harm. The eardrum ruptures at 190 decibels, and death will occur at 200.
Horses hearing is much more keen than that of a humans, as sensitive ears are required to pick up any noices a predator may make.
a horse hears from 14 Hz to 25kHz
It's eyes and ears.
1,000 to 120,000 but sometimes 210,000 hertz
Dogs can hear sounds we can't hear because the human ear can hear from 20-2000 Hertz. Dogs instead can hear higher/lower. It's all because of the hearing and how many hertz we can hear.
20 Hertz to 20,000 Hertz is the frequency response range that a human can hear. So in answer to your question 20 Hertz would be the lowest pitch a human can hear.
Probably between 16000 and 22000.
20 hertz to 20,000 hertz
These units are not measuring the same things. Hertz is a frequency unit and horsepower is a power unit. It's a little like asking "how many gallons in a foot."
No they have an aversion to high pitched noises.

Yes, a horse can hear.
The nominal human hearing range is 20-20,000 Hz.
i think 20 to 45,000
A human ear can pick up a sound of up to 20,000 hertz. Cats can pick up 60,000 hertz, and dogs can pick up 40,000 hertz maximum.
