Hi Seasmith

Thanks for your question. Tracking these linear features can initially be done with maps inside your house in two ways. Either by extending known lines into the unknown areas or by looking for related features in unknown areas. Related features are typically areas of relative high ground. This is ground that is noticeably higher than its surroundings. A single 100 foot hill sticking out from a wide flat expanse of land for example is where these linear sound energies are naturally drawn to. Aside from these, other sacred places like churches and holy wells can be found and if you have enough of these in a line, you then have something worth investigating on the ground. To test where they are in the field, there are also a variety of ways. The scientific route, and the slow route, is to use a transducer to change the sound back into electrical energy again. The quicker way is to make sounds yourself by humming. As you go up and down the frequencies you will notice whether there is any resonance or not. Resonance here is indicated by tingling sensations in your fingers and other parts of your body and this occurs when your frequency matches the higher harmonic of the underlying sound. If you do not get any resonant feeling, you are most likely not above one of them. This method requires an ability to raise one's awareness. There are further practical ways of defining the different frequencies of the energies but you would need to find someone to teach you them. The next important thing is to find someone else who can do the same thing and get them to also check the same area you did without sharing any results. Only when the two sets of results are compared can you begin to be sure that the sound energy concentrations are there or not.
