• Esi and Yasemin defined the metric spaces  , ,  , and  lp(f, p, s) of sequences of interval numbers by a modulus function. In this study, we consider a generalization for double sequences of these metric spaces by taking a ψ function, satisfying the following conditions, instead of s parameter. For this aim, let ψ(k, l) be a positive function for all k, l ∈ N such that (i)  (ii)  or ψ(k, l) = 1.

  Therefore, according to class of functions which satisfying the conditions (i) and (ii) we deal with the metric spaces   and  of double sequences of interval numbers defined by a modulus function.
