Sounds involving liquid sources are part of everyday life. They form a category of sounds easily identified by human listeners in different experimental studies. Unlike acoustic models that focus on bubble vibrations, real life instances of liquid sounds, such as sounds produced by liquids with or without other materials, are very diverse and include water drop sounds, noisy flows, and even solid vibrations. The process that allows listeners to group these different sounds in the same category remains unclear. This article presents a perceptual experiment based on a sorting task of liquid sounds from a household environment. It seeks to reveal the cognitive subcategories of this set of sounds. The clarification of this perceptive process led to the observation of similarities between the perception of liquid sounds and other categories of environmental sounds. Furthermore, the results provide a taxonomy of liquid sounds on which an acoustic analysis was performed that highlights the acoustical properties of the categories, including different rates of air bubble vibration.
涉及液体声源的声音是日常生活的一部分。在不同的实验研究中，它们构成了一类很容易被人类听众识别的声音。与专注于气泡振动的声学模型不同，现实生活中液体声音的实例，比如由含有或不含有其他物质的液体产生的声音，非常多样，包括水滴声、嘈杂的水流声，甚至固体振动声。让听众将这些不同的声音归为同一类别的过程仍不清楚。本文提出了一项基于对家庭环境中液体声音进行分类任务的感知实验。它旨在揭示这类声音的认知子类别。对这一感知过程的阐明导致观察到液体声音的感知与其他类别的环境声音之间的相似性。此外，研究结果提供了一个液体声音的分类法，并在此基础上进行了声学分析，突出了各类别的声学特性，包括不同的气泡振动速率。
