Prominent places were powerful places. The persistence and stability of prominent places typically depends upon the prioritisation of their physical and visual attributes. Yet if we are interested in the expression of prominence and power, then we should take account of the potential ways that places reached acoustically into the landscape. Acoustics complement visibility since sound like sight helps shape human experiences, memories and emotions. In this paper, we employ a geospatial framework where patterns of sound propagation are modelled and brought into conversation with visibility and mobility-based analyses often applied in geospatial studies of prominence. We apply our approach to a study of the Bryn-y-Castell hillfort in North West Wales. Geospatial studies, employing viewshed and least-cost modelling, examine how topographic and visual exposure might have accentuated the presence of hillforts. We demonstrate the analytical value of combining acoustic, visibility and mobility approaches in mapping zones in which a trade-off in visual and acoustic messages may have been a feature of how landscape prominence was expressed. The contribution of this study lies in challenging us to think, conceptually and methodologically, of prominence as something that varied, was ephemeral, and that lost and gained potency with intensities of inhabitation and landscape dynamics.

显赫的地方是强大的地方。显着位置的持久性和稳定性通常取决于其物理和视觉属性的优先级。然而，如果我们对突出和权力的表达感兴趣，那么我们应该考虑到地方在声学上进入景观的潜在方式。声学补充了可见性，因为声音像视觉有助于塑造人类的体验、记忆和情感。在本文中，我们采用了一个地理空间框架，其中对声音传播模式进行了建模，并与通常应用于突出地理空间研究的基于可见性和移动性的分析进行对话。我们将我们的方法应用于威尔士西北部 Bryn-y-Castell 山丘的研究。地理空间研究，采用视域和最低成本建模，检查地形和视觉暴露如何突出山丘的存在。我们展示了在绘图区域中结合声学、可见性和移动性方法的分析价值，其中视觉和声学信息的权衡可能是景观突出表现方式的一个特征。这项研究的贡献在于挑战我们在概念上和方法上思考突出作为一种变化的、短暂的、随着居住和景观动态的强度而失去和获得效力的东西。
