AB  - With the work of Wallace C. Sabine on the lecture hall of the Fogg Art Museum and
      concert hall of Boston Symphony Hall, a foundation for the field of architectural
      acoustics as a science was laid between 1895 and 1900. Prior to that, architects 
      employed various notions in acoustic design. Previous studies by the authors have
      reviewed 18th and 19th century design guidelines that were based on the
      quantification of the perception threshold between direct sound and first order
      reflections, with these guidelines being followed in the design of several rooms 
      with acoustical demands. This study reviews an alternate metric guideline, based 
      on the directivity and propagation distance of the human voice, which was
      utilized in several halls also during the 18th and 19th centuries. The related
      acoustic experiments tested how far sound was perceivable towards the front,
      sides, and rear of a speaking person. These ratios were used in the acoustical
      design of at least five lecture halls, four theater halls, one opera hall, and
      one concert hall, constructed in Germany, England, and the USA. These historic
      designs, and comparisons to modern measures and guidelines, are reviewed.
