Calculator for real hydroacousticians! The value mentioned noise decibels. Калькулятор гидроакустика is offered by Black Inet Cat. Last Updated: March 08, 2016. Current Version: 2.3
Scientific calculator, facilitates the calculation of sonar.
It allows you to:
– Recalculate the sound pressure to standard conditions and vice versa;
– Calculate the value of dB power and pressure;
– Calculate the pressure value, expressed in decibels relative to the threshold of audibility;
– To perform trigonometric calculations,
– Produce value transfer from radians to degrees and vice versa;
and other engineering calculations.
VI – enter the order number;
+, -, ×, ÷ – standard arithmetic operations;
sin, cos, tan – trigonometric functions,
asin, acos, atan – inverse trigonometric functions,
n – output of Pi,
y ^ x – exponentiation;
mod – calculation of the remainder of the division;
ln – natural logarithm calculation base;
log10 – calculation of the logarithm to the base 10;
log2 – calculation of the logarithm to the base 2;
e ^ x – exponent calculation;
1 / X – the calculation of the inverse value of the number;
\ R – calculation of the value of the square root of;
X-> M – record numbers in the memory;
M-> X – call the number from memory,
° ~> rad – translation degree value to radians,
rad ~> ° – translating radians to degrees,
Pf ~> P1 – recalculation of noise pressure to standard conditions;
P1 ~> Pf – sound pressure conversion from standard conditions;
To convert sound pressure values should fill the center frequency, bandwidth, and concentration factor.
X-> F0 – enter the mean frequency (in Hz);
X-> Df – input processing bandwidth value (in Hz);
X-> Kk – coefficient of input concentrations.
K ~> dB – the number of transfer times number of decibels (largest);
dB ~> K – translation from among decibels (largest) in the number of times;
K ~> dBm – the number of transfer times number of decibels (largest);
dBm ~> K – translation from among decibels (largest) in the number of times;
P ~> dB – translation pressures in decibels relative to the threshold of hearing (2 × 10 ^ -5 Pa)
dB ~> P – translation decibel values are relative to the threshold of hearing (2 × 10 ^ -5) in the amount of pressure;
pp ~> Ud – translation of the full amplitude of the amplitude (pk-pk) sine wave voltage to the current value of the voltage;
Ud ~> pp – translation of the current value of the voltage (UD) of the sinusoidal signal of the full swing swing amplitude (pk-pk).
