Egg cartons have been used as sound-absorbing materials since the 1970s for the acoustic control of music recording studios and small private radios. Egg cartons are recyclable materials made with waste from the separate collection of paper and could be valid sound-absorbing systems to be used in a simple and inexpensive way for room acoustic correction. This paper reports the acoustic measurements performed inside a room whose initial reverberation time was over 2 seconds at mid-frequency. After the introduction of 10 square meters of egg cartons, the reverberation time dropped to 1.1 seconds. The study confirms that egg cartons are suitable for sound-absorbing, especially at medium and high frequencies. This paper also reports the measurements of the sound absorption of eff cartoons using the impedance tube and in a reverberant environment.

Abstract
Egg cartons have been used as sound-absorbing materials since the 1970s for the acoustic control of music recording studios and small private radios. Egg cartons are recyclable materials made with waste from the separate collection of paper and could be valid sound-absorbing systems to be used in a simple and inexpensive way for room acoustic correction. This paper reports the acoustic measurements performed inside a room whose initial reverberation time was over 2 seconds at mid-frequency. After the introduction of 10 square meters of egg cartons, the reverberation time dropped to 1.1 seconds. The study confirms that egg cartons are suitable for sound-absorbing, especially at medium and high frequencies. This paper also reports the measurements of the sound absorption of eff cartoons using the impedance tube and in a reverberant environment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
