When designing outdoor spaces for archaeoacoustics—studying how ancient structures interact with sound—durability is key. The furniture must withstand harsh weather while preserving acoustic integrity. Here are the top materials:

1. Teak: Naturally resistant to moisture and decay, teak maintains its structural integrity and acoustic properties over time.

2. Stainless Steel: Rust-proof and sturdy, it’s ideal for frames, though cushions may need weather-resistant fabrics.

3. Polyethylene (HDPE): Recyclable and UV-resistant, HDPE mimics wood but won’t warp or fade, ensuring long-term acoustical performance.

4. Concrete: Heavy and weatherproof, concrete benches or tables can enhance sound reflection in open-air settings.

5. Aluminum: Lightweight yet durable, powder-coated aluminum resists corrosion and complements modern acoustic designs.

For archaeoacoustic applications, prioritize materials that balance longevity with sound-enhancing qualities. Combining these with strategic placement can create immersive outdoor soundscapes.
