چکیده

صدا به عنوان یک عامل زیان‏آور در محیط‌های کاری می‏تواند علاوه بر مشکلات جسمی، به لحاظ آسایشی نیز شرایط آزاردهنده‏ای برای افراد ایجاد نماید. بنابراین علاوه بر ارزیابی پارامترهای کمی همچون تراز فشار، شدت و توان صدا، بررسی پارامترهای کیفی صدا در محیط‏های کاری نیز کاملا ضروری به نظر می‏رسد. در این مقاله، مهمترین معیارهای کیفیت صدا یعنی بلندی، تیزی، زبری و قدرت نوسان معرفی شده و روابط هر یک از آنها ارائه شده است. همچنین مدل‏های شناخته شده آزردگی صوتی یعنی مدل بی‏طرفانه، سایکوآکوستیک و سایکوآکوستیک اصلاح‏شده نیز مورد بررسی قرار گرفته‏اند. از آنجایی که افزایش آسایش صوتی تاثیر بسزایی در افزایش کارآیی افراد دارد لذا پرداختن به مقوله کیفیت صدا علاوه بر کمیت صدا در تحقیقات آتی ضروری به نظر می‏رسد.
