  The Minkowski sum of two subsets $A$ and $B$ of a finite abelian group $G$ is
defined as all pairwise sums of elements of $A$ and $B$: $A + B = \{ a + b : a
\in A, b \in B \}$. The largest size of a $(k, \ell)$-sum-free set in $G$ has
been of interest for many years and in the case $G = \mathbb{Z}/n\mathbb{Z}$
has recently been computed by Bajnok and Matzke. Motivated by sum-free sets of
the torus, Kravitz introduces the noisy Minkowski sum of two sets, which can be
thought of as discrete evaluations of these continuous sumsets. That is, given
a noise set $C$, the noisy Minkowski sum is defined as $A +_C B = A + B + C$.
We give bounds on the maximum size of a $(k, \ell)$-sum-free subset of
$\mathbb{Z}/n\mathbb{Z}$ under this new sum, for $C$ equal to an arithmetic
progression with common difference relatively prime to $n$ and for any two
element set $C$.
