Plz make a video on What is incrimination? How to control air pollution? Fume hood? Baseline survey for any project? Fabric filter? Dust adsorption? (In the field of Environment)
Some time I have to go in distillery plant near turbine , centrifugal running condition pumps I think ear plug is not enough to protect ear from noise more than 100 decible in this situation which ear plug insuitable to protect ear above 100 to 130 decible
Actual me three type hi hota hai. But tmhre syllabus me sonic sound krke bhi diya hua hai. To sonic sound ka ye definition ho skta hai- Waisa noise jiska mach number 1 ho jaye. Means speed of given sound speed of sound in standard medium ke equal ho jaye then mach no. 1 ho jata hai. Tb us sound ko sonic sound bol skte hai.
Mach no. Se pta chalta hai ki koi bhi element sonic hai, ya hypersonic, ya supersonic. For example - Air me sound ki maximum speed 320 km/s ke around hai Air me agr hame koi aisa noise mile jiski speed 320 ke around ho tb mach no. 1 ho jata. Bcz dono ka speed same hai. Maximum speed ke equal ho gya us sound ka speed. Us condition me bole ge ki sonic noise hai
There r 2 formula for sound intensity in dB. I hav collected this data from standard book and verified from many sites. If u will take amplitude then u hav to take 20 log (....). So, u r also right. But not in terms of power. For calculating sound intensity in decibel, my formula is correct. U can check it on many sites and book.
Bahut bahut badhiya Bhaiya
Bilkul sahi tarike se aur ek ek point bataya aapne I'm very excited 😊😊😊😊😊😊
😊
Sources, weighting networks, measurement of noise indices (Leq, L10, L90,
L50, LDN, TNI) ye topic ka video bna diye
bhai... bahut achhe.... appreciation...
Shukriya bhai
this video improve my basic problem of noise measurment….Sir i wanna notes on vibration and unit conversion of noise.
Thank you!!
😊
Plz make a video on
Noise level at residential area?
Noise level at industrial area?
Plz make a video on
What is incrimination?
How to control air pollution?
Fume hood?
Baseline survey for any project?
Fabric filter?
Dust adsorption?
(In the field of Environment)
Can we use a mobile app to measure noise levels anywhere?
Yes.
There are some mobile apps. U can search in play store or google.
So great lacture sir
😊
Thanks sir 🔥🔥🔥
Sir thanks so much your teaching style is amazing
R u from which college? 😊
Thanks..keep it up 👍
कितनी दूरी से साउंड लेवल मापना चाइये as per act
For accurate measurement, 1 to 3 meters from source.
what language is this ?
how to record the noise in the instrument
Thanks
Sir , ..what is intensity of reference sound ?
10 to the power minus 12 w/ m2
WHAT IS THE PRISE SOUND MEASURE INSTRUMENT
Some time I have to go in distillery plant near turbine , centrifugal running condition pumps I think ear plug is not enough to protect ear from noise more than 100 decible in this situation which ear plug insuitable to protect ear above 100 to 130 decible
Sir sonic noise Nahi bataye ?
Actual me three type hi hota hai.
But tmhre syllabus me sonic sound krke bhi diya hua hai.
To sonic sound ka ye definition ho skta hai-
Waisa noise jiska mach number 1 ho jaye.
Means speed of given sound speed of sound in standard medium ke equal ho jaye then mach no. 1 ho jata hai.
Tb us sound ko sonic sound bol skte hai.
@@EngineersAadhar Mach no. 1 samajh me Nahi aa Raha hii sir
Mach no. Se pta chalta hai ki koi bhi element sonic hai, ya hypersonic, ya supersonic.
For example - Air me sound ki maximum speed 320 km/s ke around hai
Air me agr hame koi aisa noise mile jiski speed 320 ke around ho tb mach no. 1 ho jata.
Bcz dono ka speed same hai.
Maximum speed ke equal ho gya us sound ka speed.
Us condition me bole ge ki sonic noise hai
Sir air pollution ka part B ,18 marks ka hii vo bata dete to 18 marks clear ho jata sir please
Part B ka bs ek automobile wala hi remaining hai
Baki sara ho gya hai. Automobile ka last me kra dun ga.
Don't worry
wrong formula Kyu sikha raheho bhai ??? 20 log * (power1/power2) is the correct formula
There r 2 formula for sound intensity in dB.
