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 'uneventful' yn groes i 'eventful', a rhwng 'calm' a 'monotonous'. 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.
