Commentary for Berakhot 29:11
תנן התם חרש המדבר ואינו שומע לא יתרום ואם תרם תרומתו תרומה
We have learnt elsewhere in the Mishnah : A deaf man who speaks but cannot hear may not separate the Terumah ; but if he has done so, his Terumah is valid.
Abraham Cohen Footnotes to the English Translation of Masechet Berakhot
Because the act was accompanied by the saying of a benediction which the deaf man would not be able to hear.
