Context: Seinweddau llonydd: dylai'r rhain fod â ffynonellau naturiol lefel-isel pell, a rhywfaint o awel ysgafn; nifer gymharol fach o ffynonellau, ystod amledd cytbwys, amrywiadau amser araf, dechrau a stopio’n araf a chymedrol, fel nad yw ffynonellau newydd neu rai sy'n diflannu yn gwneud gwahaniaeth mawr; mae hymian dinas yn dal i fod yn dderbyniol, ar yr amod ei fod ar lefel isel iawn ac yn bell.
Notes: Un o wyth disgrifydd ar gyfer nodweddion canfyddiadol seinweddau, at ddiben gwneud ymchwil i seinweddau'n unol â ISO/TS 12913-2:2018. Pennwyd y disgrifyddion Cymraeg drwy'r Soundscape Attributes Translation Project (SATP), a arweinir gan UCL, mewn cydweithrediad â Llywodraeth Cymru. Gosodir y nodweddion canfyddiadol ar fodel cylchbleth, lle mae gan bob nodwedd un sy'n groes iddi, a lle mae perthynas rhwng nodweddion sydd nesaf at ei gilydd. Mae 'calm' yn groes i 'chaotic', a rhwng 'pleasant' ac 'uneventful'. Lle ceir dau ansoddair Cymraeg, mae'r ddau i'w defnyddio gyda'i gilydd, yn hytrach na defnyddio'r naill neu'r llall. Gweler y maes Cyd-destun am ddisgrifiad safonol o'r nodwedd ar sail deunyddiau'r SATP. Gweler https://tinyurl.com/cylchblethseinwedd am ddyluniad o’r model cylchbleth Saesneg.
