Sensor notes

Sound sensor

db son una unidad que mide la ratio entre una unidad de ref y una de entrada. además son una unidad logarítmica, su incremento no es lineal, esto es útil pq el rango de representación es muy grande

importante no liarse entre db's de potencia y db's de presión sonora http://en.wikipedia.org/wiki/Sound_pressure

para calcular los dB (dB así a secas es potencia o sea W) dB = 10 * Log (PowerInput/ PowerReference)

de momento yo he probado de calcular dBv... prueba el código y dime el que

int dBv = 20 * log(analogRead(A0) / 0.00378787879); // esto es dBv = 10 * Log (Vrms / Vrms referencia) // 0.00378787879 sale de considerar que 0dBv son 0.775V

también así a saco al igual podrías probar

int dBv = 20 * log(analogRead(A0) / calibration);

calibration saldría de comparar con el iphone…

para probar...

int cycles = 20; long reads = 0; int average = 0; double dB = 0;


void setup() {

 Serial.begin(9600);

}

void loop(){

 for (int i=0; i >= cycles; i++){
   reads = analogRead(A0) + reads; 
 }
 average = reads / cycles;
 reads = 0;
 dB = 20*log10(average/250);
 Serial.println(dB, DEC);

}


en principio el valor tendría que ser el valor RMS pero como no queremos medir una onda súper precisa sino ruido ambiental yo creo que podría funcionar a saco.

aun así medir dB directamente con el ADC por lo que he leído no es nada fácil pq en seguida te quedas o a 0 o te quedas saturado, 1023. estos se podría solucionar con un amplificador logarítmico algo que es como un op amp normal berita news pero que en vez de amplificar la senyaseñall linealmente (como una multiplicación) la amplifica exponencialmente por lo que cuanto más pequeño es el número más resolución te da.
