What is the audible frequency range for the human ear?
What is the audible frequency range for the human ear?
मानव कान के लिए श्रव्य (सुनाई देने वाली) आवृत्ति सीमा क्या है?
Detailed Solution & Logic
20- 20,000 hz
Explanation
The human ear can typically hear sounds in the frequency range of 20 Hz to 20,000 Hz (20 kHz).
- Sounds below 20 Hz are called infrasound (not audible).
- Sounds above 20,000 Hz are called ultrasound (also not audible to humans).
मानव कान सामान्यतः 20 Hz से 20,000 Hz (20 kHz) तक की ध्वनियों को सुन सकता है।
- 20 Hz से कम ध्वनि को इन्फ्रासाउंड कहते हैं (जो सुनाई नहीं देती)।
- 20,000 Hz से अधिक ध्वनि को अल्ट्रासाउंड कहते हैं (जो मानव नहीं सुन सकता)।
Why other options are incorrect / अन्य विकल्प गलत क्यों हैं
- 0 – 10,000 Hz ❌ → बहुत कम रेंज, पूरी श्रवण सीमा नहीं।
- 2 kHz – 20 kHz ❌ → निचली आवृत्तियाँ (20–2000 Hz) छूट जाती हैं।
- 100 – 1000 Hz ❌ → केवल मध्यम रेंज को दर्शाता है।
⭐ Extra Facts / अतिरिक्त तथ्य
- Young people can hear closer to 20 kHz, but this limit decreases with age.
उम्र बढ़ने के साथ सुनने की क्षमता कम हो जाती है। - Dogs can hear up to around 40–60 kHz, much higher than humans.
कुत्ते इंसानों से ज्यादा उच्च आवृत्ति तक सुन सकते हैं।
✔️ Final Answer: 20 – 20,000 Hz
