Rydym am annog trigolion i drosglwyddo o wresogi tanwydd ffosil i ddewisiadau eraill carbon isel, ond heb greu niwsans sŵn.  Felly, gwnaethom gomisiynu arbenigwyr acwstig i ymchwilio i'r rhesymeg pellter hwn, i gaffael ac adolygu tystiolaeth gysylltiedig, ac i argymell a ddylid newid yr hawliau datblygu a ganiateir.
We wish to encourage residents to transition from fossil fuel heating to low carbon alternatives, but without creating noise nuisance.  Therefore, we commissioned acoustics experts to investigate this distance rationale, to obtain and review related evidence, and to recommend whether the PDRs should be changed.
