Short answer. Yes, sometimes. Under Rule 130, Section 33, an act or declaration made in your presence and hearing may be given in evidence against you if you said or did nothing, the statement naturally called for action or comment if untrue, and it was proper and possible for you to respond. Every condition must be met.
What the law says
An act or declaration made in the presence and within the hearing or observation of a party who does or says nothing when the act or declaration is such as naturally to call for action or comment if not true, and when proper and possible for him or her to do so, may be given in evidence against him or her.

The rule on admission by silence
The Rules on Evidence treat some silences as speech: An act or declaration made in the presence and within the hearing or observation of a party who does or says nothing when the act or declaration is such as naturally to call for action or comment if not true, and when proper and possible for him or her to do so, may be given in evidence against him or her. The logic is human enough — an innocent person confronted with a false accusation would ordinarily protest. But the rule converts silence into evidence only when its conditions are all satisfied, and each one limits it.
What must be true before silence counts
First, the act or declaration must have happened in your presence and within your hearing or observation — an accusation made behind your back, or one you never actually heard or understood, is outside the rule. Second, it must be one that naturally calls for action or comment if not true: a direct accusation of wrongdoing does; a passing remark, an ambiguous comment or ordinary gossip may not. Third, responding must have been proper and possible at the time. Silence in a moment of shock, fear or confusion, or where you had no real opportunity to speak, is not the calm, telling silence the rule contemplates.
When staying quiet proves nothing
The proper and possible condition carries most of the weight. There are settings where the law itself expects or protects silence — a person under investigation for a crime has the right to remain silent and to counsel, and silence exercised as a right is not the natural, unexplained muteness the rule is aimed at. The same goes for situations where speaking up would have been out of place: formal proceedings where you speak through counsel, or confrontations where any answer could be twisted. In short, the rule reaches the silence of someone who could and should have spoken, and chose not to.
If this is being used against you
Reconstruct the moment precisely, because the conditions are factual. Where were you, what exactly was said, did you actually hear it, who else was present, and what made responding improper or impossible — fear, advice of counsel, the setting, the speaker's authority. Admission by silence is not conclusive even when admitted; it is one piece of evidence, to be weighed, and its force depends entirely on how natural a denial would have been. A lawyer will want the full context of the confrontation, not just the fact that you said nothing.
