A number of sound absorbing baffles are added under the ceiling, causing the reverberation time to drop to T2=1+D/10 s. Compute the total absorption area of one baffle, knowing their number N=10+E.	OK value	OK unit	Score	3) In a standing wave tube a pure tone at 1000 Hz is generated. The maximum value of SPL is 80+F dB and the minimum value is 70+E dB. Compute the sound absorption coefficient α of the sample according to ISO 10534.	SWR	OK value	Score	4) A sound intensity probe is placed in front of an absorbing surface. The Sound Intensity Level in the 1 kHz octave band is 75+F/2 dB, while the Energy Density Level is 80+E/2 dB. Compute the sound absorption coefficient α of the sample with the Sound Intensity method.	rE	OK value	Score	5) A truck passage was recorded, with a total duration of 70+F s and an Leq = 65+E dB(A). Compute the value of SEL	OK value	OK unit	Score	6) After a 24h measurement of environmental noise, the following three values are found: LA,eq,day = 60+F dB(A), LA,eq,evening = 60+E/2 dB(A), LA,eq,night = 55+D/2 dB(A). Compute the value of LDEN.	OK value	OK unit	Score	7) What's the decay rate with distance for a point-like source ?	Score	8) What's the decay rate with distance for a line source ?	Score	Total SCORE
