Abstract

Bir gürültü bastırıcısı bir birinci ve ikinci mikrofon sinyalinin bir frekans dönüşümünden bir birinci ve ikinci frekans alanı sinyalini oluşturmak için bir birinci (401) ve bir ikinci (403) dönüştürücüyü içerir. Bir kazanım ünitesi (405, 407, 409) birinci frekans alanı sinyalinin büyüklük zaman-frekans döşeme değerleri ve ikinci frekans alanı sinyalinin büyüklük zaman-frekans döşeme değerleri için zaman-frekans döşeme kazanımlarını belirler. Bir ölçeklendirici (411) zaman-frekans döşeme kazanımları tarafından birinci frekans alanı sinyalinin zaman-frekans döşeme değerlerinin ölçeklendirilmesi aracılığıyla bir üçüncü frekans alanı sinyalini oluşturur; ve sonuçtaki sinyal bir üçüncü dönüştürücü (413) tarafından zaman alanına dönüştürülür. Bir düzenleyici (405, 407, 415) konuşma döşemeleri veya gürültü döşemeleri olarak birinci frekans alanı sinyalinin zaman-frekans döşenelerinin atamasını yapar; ve kazanım ünitesi (409) konuşma döşemeleri veya gürültü döşemeleri olarak zaman-frekans döşemelerinin atanmasına yanıt olarak kazanımları belirler.
