nepal standard time

in 1956 we  set our watches for the first time to Nepal Standard Time, with the meridian at Mt Gauri Shankar located at dolakha district, 100km east of Kathmandu.  baisakh 1 2042   Saturday, April 13, 1985 A.D.  +5h45m set It was a choice to set our clocks 10 minutes ahead of India, which at the time used the longitude that passed through Calcutta. When our Neighbour switched their meridian to Hyderabad in 1971, we officially had four degrees of separation, hence a further five minutes ahead of the Indian time was because Gauri Shankar was closer to Nepal's center of gravity,  Gaurishankar longitude: 27°57′12″N 86°20′09″E choosen 86'15''   =86+15/60 86.25 time diff =  86.25 * 4 min =  345 min = 5 hr 45  nepal lies between 26 °22' - 30 °27' north latitude and 80 °4' - 88 ° 12' east longitude maldives tz UTC+5 india UTC+5:30

 sound is pressure waves. it propagates based on pressure difference longitudinal wave, amplitude of oscillation is in direction of propagation human hearing range 20-20khz female higher frequency , so it reaches longer distance  sound is perceived when vibration in air is detected by ear. ear converts vibration to electrical impulse impulses are transmitted to brain by nervous system and brain detects pitch,timber and loudness   sound travel by compression and rarefaction of air molecules   v -= sqrt(T) T is in kelvin   v1/v2=sqrt(T1/T2)   at 20 degree 344 m/s   measurment Lp=20 log (p/p0) p0=refrence pressure 2*10^-5  which is often considered as the threshold of human hearing (roughly the sound of a mosquito flying 3 m away).  Lw=10log(w/w0) w0=10^-12 W Li=10log(i/i0) i0=10^-12 W/m^2     Intensity of sound unit W/m^2 threshold of hearing intensity = 1 pico W/m^2   threshold of pain = 10 W/m^2 , pressure 63 N/m^2   phon loudness of sound intensity in db over threshold of hearing at 1
