Dipanwita Majumdar,Himadri Tanaya Dasc enclosed volume coupled through a small orifice to the outside space. Resonance takes place when the system is excited by a frequency that is a function of the enclosed volume and the ratio of the volume and orifice diameter. The assumption is made that the thickness of the enclosure is negligible

Noise and Vibration from Railroad Traffic,om the desired amount of noise loss. In Figure 16A, S represents a line source, such as a busy freeway, and the barrier is actually a long wall viewed along its end. R represents a target residence where a certain amount of sound attenuation is desired, as compared to the case where there is no barr

Rosella Fattori M.D.,Marco Di Eusanio M.D.Figure 5 shows the energy attenuation constant, m, in inverse meters (m.) as a function of frequency and relative humidity. In this form, the data can be used to determine the effects of atmospheric losses on reverberation time at high frequencies.
