Upright pianos can seem louder due to their acoustic design. Unlike grand pianos, where the soundboard is flat and large, the soundboard in an upright piano is smaller and curved. This means the sound waves have less distance to spread out, resulting in a louder and more focused sound. Additionally, the strings in an upright piano are usually thicker and tighter than those in a grand piano of similar size, which contributes to the louder sound.
