In this paper we study the problem of counting Salem numbers of fixed degree. Given a set of disjoint intervals I 1 , . . . , I k ⊂ [0; π], 1 ≤ k ≤ m let Sal m,k (Q, I 1 , . . . , I k ) denote the set of ordered (k + 1)-tuples (α 0 , . . . , α k ) of conjugate algebraic integers, such that α 0 is a Salem numbers of degree 2m + 2 satisfying α ≤ Q for some positive real number Q and arg α i ∈ I i . We derive the following asymptotic approximationproviding explicit expressions for the constant ω m and the function ρ m,k (θ). Moreover we derive a similar asymptotic formula for the set of all Salem numbers of fixed degree and absolute value bounded by Q as Q → ∞.
