Its propagation must rely on a medium (such as air, water, or solids) and cannot occur in a vacuum. When a sound source (for example, an ultrasonic transducer) vibrates, it causes periodic compression and rarefaction of the surrounding medium particles, thereby forming a longitudinal wave that propagates through space.\nOne key characteristic of sound is its frequency, which refers to the number of vibrations of a sound wave per second, measured in hertz (Hz). The frequency range of sound waves perceptible to the human ear is approximately from 20 Hz to 20 kHz.\nWhen the frequency of a sound wave exceeds 20 kHz, it is referred to as <a href=\"https:\/\/en.wikipedia.org\/wiki\/Ultrasound\/\" target=\"_blank\">ultrasonic sound<\/a>. This type of high-frequency sound wave lies beyond the upper limit of human hearing. Although it cannot be perceived directly by the human ear, it can be precisely generated and detected by electronic devices.<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-image stk-block-image has-text-align-center stk-block stk-6d8d68f\" data-block-id=\"6d8d68f\"><style>.stk-6d8d68f .stk-img-wrapper{width:100% !important;}<\/style><figure><span class=\"stk-img-wrapper stk-image--shape-stretch\"><img loading=\"lazy\" decoding=\"async\" class=\"stk-img wp-image-5937\" src=\"https:\/\/issrsensor.com\/wp-content\/uploads\/2025\/11\/sound-frequency-range-humans-elephants-bats-dolphins-ultrasound.webp\" width=\"1194\" height=\"662\" alt=\"sound-frequency-range-humans-elephants-bats-dolphins-ultrasound\" srcset=\"https:\/\/issrsensor.com\/wp-content\/uploads\/2025\/11\/sound-frequency-range-humans-elephants-bats-dolphins-ultrasound.webp 1194w, https:\/\/issrsensor.com\/wp-content\/uploads\/2025\/11\/sound-frequency-range-humans-elephants-bats-dolphins-ultrasound-300x166.webp 300w, https:\/\/issrsensor.com\/wp-content\/uploads\/2025\/11\/sound-frequency-range-humans-elephants-bats-dolphins-ultrasound-1024x568.webp 1024w, https:\/\/issrsensor.com\/wp-content\/uploads\/2025\/11\/sound-frequency-range-humans-elephants-bats-dolphins-ultrasound-768x426.webp 768w, https:\/\/issrsensor.com\/wp-content\/uploads\/2025\/11\/sound-frequency-range-humans-elephants-bats-dolphins-ultrasound-800x444.webp 800w\" sizes=\"auto, (max-width: 1194px) 100vw, 1194px\" \/><\/span><\/figure><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-7160f20\" id=\"2-1-main-physical-characteristics-of-ultrasonic-waves\" data-block-id=\"7160f20\"><style>.stk-7160f20 .stk-block-heading__text{color:var(--theme-palette-color-4, #1c1c1c) !important;}<\/style><h3 class=\"stk-block-heading__text has-text-color\">2.1 Main Physical Characteristics of Ultrasonic Waves <\/h3><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-d77cd69\" data-block-id=\"d77cd69\"><style>.stk-d77cd69 .stk-block-text__text{font-size:1rem !important;line-height:1.5em !important;font-weight:400 !important;text-transform:none !important;font-style:normal !important;font-family:\"Source Sans 3\", Sans-serif !important;}@media screen and (max-width:999px){.stk-d77cd69 .stk-block-text__text{font-size:1rem !important;}}<\/style><p class=\"stk-block-text__text\">Compared with ordinary audible sound waves, ultrasonic waves exhibit the following distinct characteristics:  <\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-a5265c2\" id=\"1-strong-beam-directivity\" data-block-id=\"a5265c2\"><style>.stk-a5265c2 .stk-block-heading__text{color:var(--theme-palette-color-4, #1c1c1c) !important;}<\/style><h4 class=\"stk-block-heading__text has-text-color\">(1) Strong beam directivity<\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-d83138b\" data-block-id=\"d83138b\"><style>.stk-d83138b .stk-block-text__text{font-size:1rem !important;line-height:1.5em !important;font-weight:400 !important;text-transform:none !important;font-style:normal !important;font-family:\"Source Sans 3\", Sans-serif !important;}@media screen and (max-width:999px){.stk-d83138b .stk-block-text__text{font-size:1rem !important;}}<\/style><p class=\"stk-block-text__text\">High-frequency sound waves have short wavelengths and concentrated energy, resulting in a small beam divergence angle.

Based on the \u201cTime of Flight (TOF)\u201d method: the sensor emits a beam of high-frequency sound waves, and when the sound waves encounter a target and are reflected back to the receiving end, the system calculates the target distance by measuring the time required for the sound waves to travel back and forth. This method has a clear physical basis, offers stable measurement performance, and is not sensitive to differences in the material of the object. Therefore, it has obvious advantages in traditional distance measurement, positioning, and presence detection tasks.  \nWhen explaining how does the ultrasonic sensor work in practical applications, the core mechanism is based on the propagation characteristics of sound waves in a medium, adopting the Time of Flight method.\nThe basic idea of this principle is as follows: the sensor emits a beam of high-frequency sound waves, which propagate through the air.

By quantifying the degree of energy attenuation of the received waveform, the system determines the extent to which the sound wave is affected by absorption, reflection, or scattering during transmission, thereby achieving material state identification and feedback control.\nThe typical applications of this principle include the following categories:\n<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-269e5a9\" id=\"1-a-href-https-issrsensor-com-products-m-12-ultrasonic-double-sheet-detection-sensor-target-blank-sheet-detection-a\" data-block-id=\"269e5a9\"><style>.stk-269e5a9 .stk-block-heading__text{color:var(--theme-palette-color-4, #1c1c1c) !important;}<\/style><h4 class=\"stk-block-heading__text has-text-color\">(1) <a href=\" https:\/\/issrsensor.com\/products\/m12-ultrasonic-double-sheet-detection-sensor\/\" target=\"_blank\">Sheet Detection<\/a><\/h4><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-669f125\" data-block-id=\"669f125\"><style>.stk-669f125 .stk-block-text__text{font-size:1rem !important;line-height:1.5em !important;font-weight:400 !important;text-transform:none !important;font-style:normal !important;font-family:\"Source Sans 3\", Sans-serif !important;}@media screen and (max-width:999px){.stk-669f125 .stk-block-text__text{font-size:1rem !important;}}<\/style><p class=\"stk-block-text__text\">When ultrasonic waves penetrate materials such as paper, film, or metal sheets, the signal energy decreases significantly as the number of layers increases.

ultrasonic sensor?<\/h5>\n  <ul>\n    <li>A1: The blind zone (or dead band) is the small area immediately in front of the sensor face where it cannot reliably measure distance. This happens because the transducer needs a tiny fraction of a second to stop vibrating after sending the sound pulse before it can switch to &#8220;listening&#8221; mode for the returning echo. Objects within this zone won&#8217;t be accurately detected.<\/li>\n  <\/ul>\n\n  <h5>Q2: What materials can an ultrasonic sensor not detect?<\/h5>\n  <ul>\n    <li>A2: Because they rely on sound echoes, ultrasonic sensors struggle to detect objects made of sound-absorbing materials like soft foam, heavy fabrics, or fluffy cotton. Additionally, targets with steeply angled or extremely smooth, spherical surfaces might deflect the sound waves away from the sensor, causing a missed reading.<\/li>\n  <\/ul>\n\n  <h5>Q3: Does temperature affect how an ultrasonic sensor works?<\/h5>\n  <ul>\n    <li>A3: Yes, the speed of sound changes depending on the air temperature, which can slightly alter distance calculations. However, most high-quality industrial ultrasonic sensors feature built-in temperature compensation. A temperature sensor continuously monitors the environment and adjusts the calculation to ensure consistently accurate measurements.<\/li>\n  <\/ul>\n\n  <h5>Q4: What is the main difference between ultrasonic and infrared (IR) sensors?<\/h5>\n  <ul>\n    <li>A4: The fundamental difference is the medium they use. Ultrasonic sensors use sound waves, making them immune to a target&#8217;s color, transparency (like clear glass or water), and lighting conditions. Infrared sensors use light, which makes them faster but susceptible to errors when detecting dark, reflective, or transparent surfaces.<\/li>\n  <\/ul>\n\n  <h5>Q5: Exactly how does a ultrasonic sensor work in dusty environments?<\/h5>\n  <ul>\n    <li>A5: Unlike optical sensors that rely on light, an ultrasonic sensor uses sound waves to detect objects. This means dust, dampness, and smoky environments do not block its signal, allowing it to work reliably where photoelectric sensors might fail.<\/li>\n  <\/ul>\n<\/div>\n\n\n\n<div
