hi I have just started studying sound and vibrations. I have a background in mechanical engineering. I am finding it difficult to understand the basics at my university. I believe I can find some help here and also to be aware of the newest developments in the field.

Orthogonality of modes It get the concept now. One more query. While doing the expansion of h(r) is it convolution that you have used ?? |

Orthogonality of modes @user17581,@daaxix If I am getting it right then it means that if two modes are orthogonal then there are independent of each others?They individually contribute to the energy of the whole system ? |

Fundamental frequency , wavelength and the length? In case of a rectangular room , is it so that the node corresponding to first fundamental will be at the center of the room. If so then how ? |

Fundamental frequency , wavelength and the length? Thanks a lot . It presents a clear picture now. So can it be generalized that for a wave in closed structure the λ corresponding to fundamental will always be the length of wavelength between two nodes and hence λ=2L and for a structure open at one end it will be between a crest and a node λ=4L. And if we have both ends open then should it be the one corresponding to two consecutive nodes ? |

Fundamental frequency , wavelength and the length? Thanks for your answer but I have some doubts.I am not able to understand when you say " sin(πx/L) has periodicity Δx=2L, and the periodicity of the wave is what we call the wavelength, so λ=2L" .I understand that it is just another way of saying that the time period is 2 pi . Why is that we need to have one half wave as the one corresponding to fundamental frequency. |

Eigen modes in a room Thanks for the link. I just have the idea but I am not able to get it completely. How is it done ? I am looking for the method and the concept behind it. |
