Abstract
resumo ?equalização automatizada de microfones? trata-se de uma calibragem de microfone automatizada que começa com calibragem de microfone de referência. as medições são representadas em escala para níveis de pressão de som (spls). o microfone de referência é posicionado próximo dos microfones internos e suas respostas de frequência são medidas. então, o cálculo de delta é feito nas sub-bandas selecionadas que incluem correção de microfone de referência e, então, um filtro de correção é definido.
