Talvez deva tentar algumas variações de ortografia:
decrease during » increase during (Expandir a busca), increases during (Expandir a busca), increased during (Expandir a busca)
during decrease » during increased (Expandir a busca), during depressed (Expandir a busca), during disease (Expandir a busca)
decrease sound » decrease sod (Expandir a busca), decrease soon (Expandir a busca), decrease and (Expandir a busca)
sound objects » and objects (Expandir a busca), sound effects (Expandir a busca), boundary objects (Expandir a busca)
decrease toc » decrease of (Expandir a busca), decrease the (Expandir a busca), decreased to (Expandir a busca)
toc decrease » to decrease (Expandir a busca), the decrease (Expandir a busca), not decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease during decrease toc decrease ) OR ( decrease NOT decrease sound objects ))*.
