This is EXACTLY the kind of recipe I had been searching for! Super easy, lots of greens, and great taste! Seriously, I used almost a 2 whole cups of spinach in mine and with the banana and milk it doesnât taste bad at all. Thanks for this recipe, it gives me no excuses not to get my greens in:) Reply.
The laws of sound physics (acoustics) or How does it work? The human ear can generally hear sounds with frequencies between 20 Hz and 20 kHz (the so called âaudio rangeâ). 20 Hz is a very low frequency while 20 kHz is a very high frequency. Examples of low frequencies in our surroundings are the bass in music or the low humming that a fan generates. Examples of high frequencies are the treble in music or the high notes of a small child.
slow measurement response: the exponential-time-averaging done in a sound level meter every 1000 milliseconds. Slow time response has been used in conjunction with C-weighting when measuring blast noise or other low frequency impulse sources and is available in most types of sound level meters.PCA Impulse Noise Study: FINAL REPORT, MAY 1991. impulse noise ranging from:  no level for impulse noise is too low to be ignored to: lack of an impulse standard does not place the public's hearing in jeopardy .
