I don't know the principle of operation, but years ago in "Popular Electronics" magazine, there was a construction article for a device that would allow you to hear super-sonic sounds like dog whistles, the sounds that insects make, etc. I think it mixed and shifted frequencies kinda like a super-heterodyne radio receiver does with RF. Like you, I'd like to have such a device. On the other hand, if a device picked up sub-sonic sounds, it would probably just pick up those "boom trucks" that all the young people drive, and in my opinion we can already hear those things from far enough away (about a mile).
Supporting ideaIndustry uses this equipment. A link is provided, but only as an example of the stuff being considered. No opinion, pro or con, is stated or implied. It's just a window to look through. Note: the stuff is kinda pricey for non-professional acquisition. Hit the www and see what else is out there.
What else can I help you with?
What are sound waves with frequencies above the normal human range of hearing?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
Sound waves with frequencies above the normal human range of hearing are called what?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
What is the range of frequencies that the human hearing system can detect?
The human hearing system can detect frequencies ranging from about 20 Hz to 20,000 Hz.
How is otosclerosis diagnosed?
Hearing loss due to otosclerosis is usually first noticed in the late teens or early twenties. Hearing loss usually occurs in the low frequencies first, followed by high frequencies, then middle frequencies. Extensive hearing tests.
Can you hear frequencies beyond the normal range of human hearing?
Yes, some animals can hear frequencies beyond the normal range of human hearing.
Do hearing looses develop at low frequencies faster or slower then they do at high frequencies?
The high frequencies suffer first, with age.
What frequencies do humans have?
Humans are capable of hearing frequencies ranging from 20 Hz to 20,000 Hz.
What is inaudible sounds?
frequencies that are out of normal hearing range.
What are the frequencies commonly affected by age-related hearing loss?
Age-related hearing loss commonly affects higher frequencies, typically those above 2,000 to 4,000 Hertz.
What is a hearing range of a healthy person?
The range of human hearing includes frequencies from about 15 to about 18,000 cycles per second. This varies from one individual to another, especially at the higher frequencies. High frequencies usually become less audible with age.
Does the platypus have good hearing?
They have an excellent sense of hearing, with a range of hearing similar to the frequencies that humans can detect, but they have the ability to hear lower frequencies than us. Its ears are located in a groove set just back from it; this groove is closed when swimming.
What is the hearing range of a healthy young person?
The range of human hearing includes frequencies from about 15 to about 18,000 cycles per second. This varies from one individual to another, especially at the higher frequencies. High frequencies usually become less audible with age.
