Using the measurements made in Section 3.4, we compute the pointtopoint transfer function from the bridge to a single point in space. The resulting response is shown in Figure 45. The spectrum of the response is shown in Figure 46. Observing Figure 45, the length of the response is close to s long. Similar to the issues addressed with the body response, having to store the entire radiation response is costly. Therefore, the methods discussed for removing spectral peaks for the body response can be directly applied to the radiation response.
Similar to how the drivingpoint admittance is used to model the transfer of energy from the string to the bridge and viceversa, the transfer function from a pointtopoint measurement of acceleration of the topplate to a point in space of pressure waves is used to affect the final sound output from our physical model.
