Pues yo q pensaba q ya estaba ampliamente aceptado q el ancho espectral del oido humano superaba los 20Khz de largo, lo q esta claro esq para un tono puro dsd luego q ninguno de nosotros llegamos a 18KHz.. pero esq hay mas q tonos puros..

un par de extractos:
"Many engineers have been trained to believe that human hearing receives no meaningful input from frequency components above 20kHz. I have read many irate letters from such engineers insisting that information above 20kHz is clearly useless, and any attempts to include such information in audio signals is deceptive, wasteful and foolish, and that any right-minded audio engineer should realize that this 20kHz limitation has been known to be an absolute limitation for many decades. Those of us who are convinced that there is critically important audio information to at least 40kHz are viewed as misguided."
"TO FULLY MEET the requirements of human auditory perception I believe that a sound system must cover the frequency range of about 15Hz to at least 40kHz (some say 80kHz or more) with over 120dB dynamic range to properly handle transient peaks and with a transient time accuracy of a few microseconds at high frequencies and 1°-2° phase accuracy down to 30Hz. This standard is beyond the capabilities of present day systems but it is most important that we understand the degradation of perceived sound quality that results from the compromises being made in the sound delivery systems now in use. The transducers are the most obvious problem areas, but the storage systems and all the electronics and interconnections are important as well."
La respuesta extendida mas alla de 20Khz adkiere mayor importancia en el caso concreto de los monitores con tweeter de cupula metalica en lugar de material blando, como es el caso del tweeter del MSP5, q por otra parte me parece una buena compra por su precio, yo mismo tengo unos en casa aunq no los haya comprado por su respuesta extendida en altas frecuencias, si no pq me gustaban como sonaban, especialmente su respuesta en transitorios.
Q conste q no me parece una cosa "importantisima" y no correria a cambiar mis monitores si estos no reprodujesen mas alla de 20Khz, pero eso de q solo lo va escuchar tu perro... en fin.. solo intento ser algo mas cientificamente riguroso...
